working with check boxes
I have a list of options for students to choose. Adjacent each option are two check boxes - yes or no. I want the students to select one or more of the check boxes before being allowed to click the button to view the hidden layer.
I'm having a problem because I can create triggers to force the students to at least check one box before revealing the hidden layer but I can't get the trigger right so that when they finally push the 'reveal' button the layer appears.
I've tried attaching my file to this discussion but for whatever reason the platform won't accept my attachment.
