Alteryx Apps - prompt user for input and return error message if value not in picklist

[hjiang1217]

Hi there, I've been wondering about how to show an error message and stop the process if a user entered value is not part of picklist - for example, attached workflow prompts user to enter a Name, if that Name is not part of the 7 Name, Alteryx should pop up an error message like "Invalid Name". I'd like to avoid chained apps if possible, and in reality that Name picklist has a lot of values so ask user to select from dropdown is not ideal. Many thanks!!

Hi @hjiang1217 

You can count the rows after filtering and then generate an error message if the count is 0.
