Hi Mike

>Yes, but to err is human. Whoever wrote that class may not know about mdot.

Yes, I agree with you completely. There are times when I have bungled up more royaly than this. What I had meant that when we are using a class we generally expect it not to blend with the underlying app (in all probablity much more sloppily coded *g*)

In all fairness if it had not been for the class I would have been much more of a headache on the forum just to get something like this working for me *vbg*.

Thanks for your response.
