It didn't work the way I wanted, but it could help if the parameters I am passing to the rule is changing. In my case, it was not evaluating the rule on button click. I don't have the code to post but you can refer to the a!validationMessage documentation.

Did you happen to read the example code contained within the Appian Documentation page I linked above? I was figuring it's pretty self-explanatory. If you have any subsequent questions then I'd actually suggest you post a code snippet and I can help you troubleshoot.

You can probably make use of the (sadly) lesser-known validation function, a!validationMessage, using the "SUBMIT" setting for the validateAfter parameter. This would go in a section-level and/or form-level validation, and should allow logic to be executed that would prevent the form from submitting and show your validation message.
