exit popup ... need to add onlick to the form submit

Hello :)

I have a java exit pop up script installed on my site, which is switched off when visitors click on internal links only by using ...

onclick = "setBunload(false)" within the <a href=

How would I go about adding onclick = "setBunload(false)" to the gravity form submit button? Currently, the pop up appears after hitting submit as the form redirects the user to another page on my site.

Any help, advice, tips would be appreciated. I've been trying to figure it out for two days, and not having much luck (I'm getting old and am not as sharp as I once was!)

Thanks all

Thank you x 1000!!!

Got it working.

Thanks again. Really appreciate the help :)
