Bob,

Thx for your response. I know that IV is the last column. Did you try
entering the formula in my post? I am using that formula in a cell
validation. It is giving me the wrong answer. I would appreciate any
help
or alternate formula suggestions you could give me. thx.

Hello all,

I am using the ISREF in a cell validation it insure users are entering
valid
range addresses. However, the ISREF is allowing invalid values. See
example
below:

=ISREF(A:WW) = True

If you type this into a cell, Excel changes the "A:WW" to "A:DE".

Since I am using this in a cell validation, the actual cell value does
not
change and the validation allows the incorrect data entry.

Does anyone know of solution/replacement formula I can use in my cell
validation.

Thanks for any help you can give me.
