How to validate a checkbox is ticked - server validation

I am using server validation to validate a form as a backup to HTML5 client side validation, which doesn't work in the iOS version of Safari. I have marked the checkbox I want to validate as required in the validation toolkit rules, but the form still submits and sends the email even if the checkbox is left unticked. I'm not sure what I am doing wrong as it works for other text/textarea fields on the form. Any pointers are appreciated.

send a copy of the page please and a link to test

I've attached the page, along with the email/form validation code. Just change the email address in the page code to one of yours to test it (line 87).

Thanks Jason

you have multiple instances of the Server Validation behavior on the page, there should only be 1. There should be one server valdation server behavior with all of the validation types defined in that one behavior


The validation show if for the required checbox is for one of the other 2 server validation server behaviors.

i would suggest removing the validation show if behaviors and the other 2 instances of the server validation behavior, leave only the first one, then recreate the validation show if behaviors.

Ah right - thank you Jason. I missed that.

you're welcome.
