How to make a set of check boxes required so that at least one has to be selected?

[KateA16]

Is there a way to make a group of check boxes required so that the user has to check one or more in order to complete the form? My specific need is for a Release of Information document. I want them to select which type of records they're giving us permission to access and there are four options. I want them to select at least one before they can submit the form.

Yes, you may need to emlpoy some javascripting.

This can be achieved using a script. You will either need to use the script to validate all the required fields in the file before continuing to submit it, or you could be a bit tricky and create a hidden text field to copy the value of the check-boxes group. If you set it as required and its default value as "Off" then it will fail the validation when no check-box is ticked.

The calculation script for it is simple:

event.value = this.getField("CheckBoxGroup").valueAsString;

(replace "CheckBoxGroup" with the actual name, of course)
