Thanks for the reply John! This triggered perfectly...once. If I click Save a second time without changing anything it goes right ahead and saves it. Upon closer examination, the "change percentage to empty" is not happening on the form. I tested it with "Fire change options only when something changes" both checked and unchecked. I tested it with changing the percentage to empty and to "0". It always triggers the first time (without exiting the cell), which it didn't before, but it isn't doing it a subsequent time and I have to believe I'm doing something wrong with the change action because I don't see it changing. Any thoughts?
Here's my rule:
When the record is saved after checking
and percentage is not equal to 100
abort the Save "Not 100 Change to 100"
change percentage to 0
