Wow, that was quick - ALL of you are awesome. I appreciate the brain power puzzling over these issues.

I did try Teylyn's solution and it does work for our workbook, as I'm sure it will for some others that have been created on this model. While I did say that it was created in 2003, I forgot to mention that I am viewing it in 2007. However, I figured out where to turn precision on in 2007 (Excel Options button\Advanced\When calculating this workbook) and it also works for getting the correct solution in 2007. We expect end users to put in their data on the sheet and we wanted to make sure that they were getting the correct output.

I will read more about the "precision" setup and pass that on to the creator of the workbook, too. I am also going to have him sign up for this forum, because I know he will appreciate what all of you do to help those of us not in the know. And to find more answers.

As I am not totally familiar with the customs of this forum yet, if I need to do anything else in regard to this post let me know.

Really AWESOME help. Again, thanks so much!
