Restore changed data in subform

[joecamel9166]

I have a subform that holds the shipping data. On my parent form, I need to place a message box that pops up if any of the data in the subform has changed.
I use this subform on multiple forms so the code cant be placed into the subform.

The code I currently have is on the btnSave_Click but it only works if the first 3 digits of the zipcode changed.

Also if that messagebox = vbno then I need the data on that form to revert back to what it originally was.

thanks

if you are watching the subform to change, then you DO want the code in the sub form.
Even if its in different master forms, the same fields cant change w/o notice, no matter the master form.

Not the answer I was looking for, But I guess I can make another subform and just enter the code in that one.

For some reason the docmd.runcommand accmdundo is throwing me an error.
also tried accmdredo with same error.

is there a command to revert changes?
or while thinking about it, maybe put the code in before update instead of after update?
