Multiple check boxes with a NOT applicable box

[Aldebrand]

Basically, as seen here, I've run into a bit of a hiccup with the form. I want the person filling it out to be able to multi select "morning/afternoon/evening" but if "not applicable" is selected, I want the checks in the other boxes to be erased. I am assuming it has to be a script to do so, I just don't know how, and I can't seem to find the answer here or on an internet search.

As the Mouse Up event of that field, enter the following script:

if (event.target.value!="Off") this.resetForm(["Morning", "Afternoon", "Evening"]);

(replace strings with actual field names, of course)

Just tested it in the preview, and worked great! Just did the same thing but in reverse for the other 3 boxes to uncheck the "N/A" if there's a check in the other ones. I have a few big ones coming up at the end of the form, so this works out handsomely.
