If default, you get an error when trying to continue, and if not, no error. However, the error is showing up on the last field of the form, not the field with the drop down default. So some further adjustment is apparently needed to get the error message to position on the correct field. </p> https://www.machform.com/forums/topic/input-validation#post-12849 Tue, 01 Nov 2011 00:39:13 +0000 christopherbrooks 12849@https://www.machform.com/forums/ <p>Thank you for the suggestion.

I want to force the user to make a selection. </p>
