Instead of all of this, put something in the "ToolTip" property, so that if you hover over the control, you get a one-line explanation. I understand what you want to do, but because of sub-form complications you are giving yourself a LOT of work for a benefit of limited scope. I'm kind of with Pat on this. Do too much and you annoy the heck out of the user. Trust me, I understand that it is a "damned if you do, damned if you don't" situation.
I get it but like I mentioned, if there is adjustment to do, if can done via the table instead of the need to release a new front end.
