I have a form variable that will be populated from a query string parameter. But I need to make sure that this value is populated and is not removed from the URL. Is there any way to require this value, perhaps by showing an error when the form loads to indicate that a required value is missing and not allow the user to submit the form?
Solved! Go to Solution.
You can create a rule to check if the query string is filled or not, if it is not then to hide the contents of the form if it is then show the contents of the form.
see this as an example.
If you would like the workflow I used please use this export key.
I see. Hide all of the fields if the parameter is empty and instead show an otherwise hidden label.
I also learned that you can export and import workflows!
