Maybe this is not allowed in LC but I have imported a preexisting pdf that I use at work. We are moving towards the tablet world and I am making a once pen and ink filled in form, digital. I have a need to check boxes to signify the task was completed but also apply an X to the box if it does not meet standards. So far I have the check boxes on the form where they need to be but I cannot adjust the variable to all three actions. First tap, display a check, second tap in same box display an X and third tap show box as empty.
