Conditional constraint on a repeat

BrennenW — Wed, 07 Feb 2024 19:27:21 GMT

Im looking to make a conditional constraint on a repeat based off a previous answer.

This is how its laid out:

More than 1?

Yes or No

If selected yes I want the repeat following to have as many repeats as possible.

If selected no I want there to be only one repeat and not let them proceed with additional repeats.

Any clue if this is possible?

Thank you

The way I do it is use a field count(somefieldinrepeat) and then put a constraint on that.

For you you can then use a if. Something like

if(picked no, countfield = 1, 1) the else is just 1 since if they pick yes then its all good.

You can play with where to place the field with constraint. I think count works inside the repeat so if you have it there is should stop them from creating a second repeat right away.

Hope that makes sense.

I guess im a little confused by what you mean. I attached my form below. I was able to get a constraint on the no answer and counting the number of repeats <1 . However, It wouldn't let me go more than 1 repeat with a yes answer. I deleted that from the form as it wasn't working.

Short answer is 'no', that isn't possible. As soon as you use the repeat_count column, you need a number. Longer answer is "kinda yes'.

This example will not work when "yes" is selected, as no number is provided, so the repeat disappears:

This example will work how you want since there is always a number, but has an extra step:

There would be other ways to do this, but this example uses the repeat_count column specifically.

Here is a sample attached. It stops the user from saving a second repeat and gives them a big red warning on why.

I have no idea why you would make a form like this just let them make 1 or more, why ask? Seems weird but I guess you have a reason.

It does not use repeat_count as that never works out.

Note the message does not fire until they pick the second question value. But if you want you can change that by adding a secret hidden field that has a default value and then do your check on that if you want. I can show this too if you do not get it.

And note you cannot stop them from going to repeat 2 but you can stop them from submitting more than 1 repeat. Best I have found. We use this a lot with the Opps too far message and it works.

hope that helps

Thanks Doug that worked!

The reason behind is to have a sort of fail safe. We work with a lot of college students or fresh out of college and its to make sure they are not entering data on accident as it could change our end results in a bad way. We typically use paper copies and it has been a headache to read their notes sometimes especially when they go back to school and you cant ask them. Appreciate the help!

Here is the other option. I swear I have got a constraint on a note to work but I guess not. I usually just leave the count shown and make it read only.
