you are the best!! If you are ever in the Bay Area I owe you a cup of coffee!!

XPath is case sensitive - that's why the expression stopped working. field3 is not the same as Field3. Why don't you get these tables moved where you want them in the schema, and rename stuff so it isn't group3, field3 & has meaningful names, and then I'll help you again w/ the validation. :)

OK I moved and renamed everything :)

Here you go!

I cannot open it. It says I need domain permissions. Worse case you can just copy and paste the rules. Sorry about that

This is because you are opening it in IP, not in design mode. Save the file locally. Right click the saved file and select Design to open in design mode. :)
