Nice Error Message

[RickM]

Is there any better way to restrict how many rows can be entered into
a repeating table/group. Using the one sample provided (Data
Validation) when the user exceeds the max allowable rows they get a
message box with a not so friendly string. I dint believe this
particular technique allows one to customize the message provided to
the user.

I tried implementing a simple rule (count(repeatinggroup/items) > X )
but can not get the number of rows using the count fundtion.

Any ideas are welcome

Thanks
