InfoPath Dev

I have 10 check boxes that all belong to same group. Since they belong to same group I only need one box checked (of the 10). Is there a function in InfoPath that allows me to use a group box and add the 10 check boxes to the group and set the rule that at least one box needs to be checked? Thank you.

By group I assume you are referring to a physical group in the DOM, and not just a conceptual group.

Are you asking whether there is a way to have one and only one box checked in the group? Or are you asking whether there is a way to know if at least one box is checked in the group? Or am I not understanding yet?

Referring to a conceptual group on the form for data entry validation.

This being the case, you will just need to write some code or rule/conditional formatting condition to test each of the 10 check boxes for what you are trying to find out.

i.e. something to the effect of:

if(checkbox1 == false && checkbox2 == false . . . checkbox10 == false) { /* None are checked */ }
