Hi Chad,
Currently ""Enter key forces form submission" " checkbox is unchecked and this doesn't help me (either it checked or unchecked in all browsers Chrome, Firwfox, Opera, IE) : [Enter] key press causes forem submit!
1. You can use Server side validation
2. You can use SQL Validation
Chad, please, can you say here what parameters from QUESTION VALIDATION http://imageshack.us/a/img829/4272/image009x.png area (I suppose you mean this under "Server side validation") can I use for this purpose and how?
Empirically I found that "Required field" doesn't validate checkbox.
Empirically I found that "Compare field" also doesn't work - I've created always checked checkbox and wanted to compare my "Agree with Terms of Use" checkbox with it but it wasn't available in "Compare field" drop down.
May be I can use "Regular expression" or custom SQL, but how?
