Using Calculated Values to populate Contingent Values

OliverIshmael

I have set up a field group with Contingent Values to help filter combo box fields on my form. For some of these fields, I am using Calculated Values to populate default values to save users time.

The contingent values function properly within the form but once the user has filled out all the fields in the field group, Field Maps displays the error: 'Value combination is invalid' and then the survey can't be saved.

Is this a known issue / is there a workaround?

Thank you @OliverIshmael. I've been able to resolve the issue.

For the Region and Site fields, your calculated expression needs to be changed to the following:
- return "1" for the Region field

- return "2" for the Site field

The reason for this is because the value above represents the code in the coded-value domain applied to those fields. When the form loads in Field Maps, you will see the correct descriptions of "North West Wales" and "Coed y Brenin Forest Park" applied and the contingent values will work successfully.

In arcade the syntax above assumes the value getting passed is the code and not the description, which is why it wasn't working previously.

Thanks

Hi @KevinBurke sorry about that, please try again.

KevinBurke

Thank you for sharing the map with me @OliverIshmael . Can you also please share the feature service to the group? The map cannot successfully load for me to see the form without it.

OliverIshmael

Thanks Kevin, I have sent you an invite.

Hi @OliverIshmael

Please use the ArcGIS Field Maps user account.

Thank you

Hi @KevinBurke do either of these users relate to you:

KevinBurke

Thank you for the video @OliverIshmael . That is similar to what I configured on my end using my data and it worked fine in my case. So therefore something else must be going on.

Is that map/data hosted in AGOL?

Can you share a copy with me to test with?

Hi @OliverIshmael

The email didn't come through for some reason. Was it zipped or just stand-alone?

The file might also just be too large.

A few options:

- You can try resending in a zip, unless that's what you already tried.

- You can capture a smaller video <10mb to see if that works

- You can share the map with me and I can test on my end following your steps.

In general I just need to see the behavior and the order with which values are chosen and I could probably repro this with my data. But I am just trying to understand the configuration.

Thank you

I have emailed it to you from Outlook which has a 20MB file attachment limit. Hopefully your ESRI email client will accept it.

KevinBurke

Hi @OliverIshmael , this may still not work given the size of the file, but you can try emailing it to me at kburke@esri.com.

Thanks

I have created a 20 second screen recording in mp4. It is 19mb but the max attachment I can post here is 9mb, so is there another way I can share this with you?

KevinBurke

Thank you for that info @OliverIshmael

Would you mind attaching a screen recording of the workflow from the mobile device? This will help me visualize the process being followed per your explanation above.

Thank you

There are 4 fields within the field group:

Calculated Values are used to populate Region and Site. Initially these are blank but once the user picks values for Access Point and Facility, then Region and Site are filled in correctly by Field Maps. However, when the user clicks to the next field it then displays the error that combination is invalid.

KevinBurke

Thank you for that information @OliverIshmael

How many fields are part of the field group?

How many of those fields are you calculating the values into as oppose to the field user manually selecting the value?

For example, I have a field group with the 4 fields for Type, CommonName, Genus, Species. When I originally configured my contingent values in Pro, there is no valid combination that includes any `Null` values. Therefore if I only calculate the values for Type = Evergreen, and CommonName = Holly Oak, then when my form loads I will see an invalid combination error, which is expected since the other 2 fields are left `Null`. If I then populate the remaining 2 fields in the field group, then the combination is valid and the error is removed.

In general when working with contingent values, if you only have a single valid combination, we will autocomplete the other fields automatically with that combination. However that only works when the values are manually chosen from the fields. If you're calculating the values, any values not calculated will need to manually selected.

Thanks

Hi Kevin, - I'll add comments below...

Thank you for sharing that information. So for clarification, in Field Maps if you utilize calculated expressions to populate the values from those contingent value fields, then you receive an error for the fields with an invalid combination. Is that correct? Yes

If you manually entered the same values for the fields instead of using calculated expressions, is the issue still reproducible? When i edit the form to remove the calculated values and then select the values manually instead, there is no problem.
How are the expressions being ran to populate the fields with values? I am using calculated expressions
Are they populated as soon as the form is loaded or does the user need to do something to trigger those values to get written? Yes, they are populated straight away once the form loads, with no input from the user.
What is an example of one of the expressions you've written to add these values to a field? Here is the calculated expression i use in the Arcade Editor:
return "North West Wales"

Are you able to share the map with us? I wish there was an easy inbuilt way to do this (to share a map with a copy of my data, while preserving the forms) but the attached warning message suggests otherwise

Thank you
