I think I tried that and no dice. Just to make sure, I did this:
From the Server Behaviors panel, I double clicked the WA Server Validations already in there. I then clicked ok on the Server Validations window that opened. I made sure to put any files that had been modified and it didn't work. I even tried clicking the refresh button from within the Bindings panel. I tried selecting the form field the server validations didn't have anything under it.
I'll attach some screenshots of my Server Validations window and Server Behaviors panel to make sure. If you need me to attach code, I can do that too.
