I want to be able to cycle a checkbox through all for possible values (0, 1, 2, & NULL) by clicking on it. I can't seem to get this to work. Also, I need to store the value into a field and the disply the checkbox properly. I've tried some code in the click event to check the current value and set the value to the next option and yes, I did include a NODEFAULT. It didn't work. Any ideas on how to do these two things?
