Hi Matt, Here's the code  I ended up using to get around this- I basically set it so that a user had to select between 1 - ### features to run the script. This way, if a user does not select between 1 and ##(say 25) , the  script will attempt to run on the entire data set, which will then throw the error message in Line 12 featureLayer = arcpy.GetParameter(0) #this line respects the selection listA =[] ##Add selected features to listA as needed if len(listA) in range (1,26): #this is the line that ensures something gets selected as long as the dataset is more than 25 features      with arcpy.da.UpdateCursor([insertlayerhere], ([comma separated fields here])) as uc:           for row in uc:                     uc.updateRow(row)      msg1= "OBJECTID(s) {0} will be InsertActionHere".format(listA) else:      msg1="Please select between 1 and 25 valid features." #pass message 1 arcpy.SetParameterAsText(1, msg1)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ """" instead of line ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍6 / passing everything into a list the following code also works:    features = int(arcpy.GetCount_management(featureLayer).getOutput(0))‍ """‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Hope this makes sense, let me know if not, I'd be happy to discuss further!  ...

Hi Ernestocd I achieved this by creating a python script from desktop and publishing as a Geoprocessing service that can then be served up in the geoprocessing widget.  Your script should contain an output that has an arcpy.AddMessage() and arcpy.SetParameterAsText() . The set parameter as text will be the thing that passes information as an output.  Here's a small snippet of what this looks like:  In the properties of the script tool,  set your parameter properties to be Type: Derived & Direction: Output (this makes sure the message you put in for SetParameterAsText() is an output) Additionally, when you are publishing your service on the Parameters tab of the Service Editor box, set the message level to Info Hope this helps! Feel free to reach out if you get stuck ... View more

Hello Chris, I ended up using a work around that identified a range of features a user could select and run the function for.My database had more than 20000 features, so I set that a selection range had to be between 1 & 200, If a user did not select anything, it would read it as if all 20000 features were selected & so the function would not run. Not the most ideal solution, but a work around nonetheless. I'd be happy to share this part of the code logic with you if it would help. ... View more

Hey Doug, do you have an example of what your UI actually looks like that runs this? Any chance you can share some of the code you used for the GP tool? And is it a PDF by PDF basis or does it work to create multiple maps? ... View more

xander_bakker‌ , yes. It should detect the selection made in the WAB by the current user.  ... View more

Hi Xander, To clarify- I am attempting to use this python code as a geoprocessing tool in AGOL webapp builder. I test from desktop before publishing as a GP service, but ultimately the script needs to work as a GP service from the geoprocessing widget in WAB. ... View more

Sure thing, do you have an email I can send to directly? ... View more

Thanks Dan, the issue with GetCount_management is that if I have nothing selected, it sees all the records in the layer so it retruns message 2 (too many features selected) instead of message1 (no features selected) ... View more

Ryan, I found a work around to help with this if you are doing it in an out of the box GP widget. . Let me know if you are still needing help with this ... View more

Grant, the solution you propose to adding a message in the Geoprocessing tool of WAB, will this work in the out of the box version of WAB or does it need to be a custom widget in web app developer? ... View more
