I was trying to say that it would be helpful to post the formula. We have a
very good forum here and try to help whenever possible. However, mind
reading is in a different forum.
Useful answers come with useful descriptions of the problem. Also, please
keep your replies, even if vitriolic, in the ng so all will benefit from
your comments.

I have taken the liberty of posting your comment to me in the ng.

So nice of you to show us all how dumb we really are! This is a free
forum. If you find the information insufficient, feel free not to
respond. Do not presume to show us the error of our ways, or if you do,
at least have the courtesy of providing some sort of useful answer to
the original question. We might not all be as savvy as you in writing
our messages. No need for sarcasm.

I am copying down a formula on my worksheet. What the formula does is
add the cells from 10 different worksheets. The formula and everything
works fine for 252 lines. However starting with line around 306 (no
information in those rows) the formula no longer adds up the cells. I
only get 0 values.

Why is it doing this????? I'm going nuts trying to get it to work!
