Now that I have my form working I need to tweak it. Is there any way to make a checkbox mandatory? I have two on the form, and only one has to be checked. It doesn't matter which one as long as one of them is checked before submitting.

Thank you.

Hi Battlecat

should just just be able to right click the control, then tick cannot be blank.

I did try that before I posted my question. The box for cannot be blank is grayed out. This would make sense since one out of two should be checked, not both. It is basically a disagree or agree to the terms check boxes.

What i would, do is make that a radio button with a set of 2 if its not already. You then should be able to make them cannot be blank.

I found my solution here:

Good call, glad you got it sorted.

Yea, me too. I do need to massage it a bit because if you check a box the submit button is usable, but if you uncheck it it is still usable. So a little tweaking and I should be good.

Thanks for your efforts
