I'm creating a workbook for someone else to use evaluating a decision. I
would like to give the user a copy of the workbook, with the ability to
change several variables throughtout the workbook, but the inabilty to
modify the calculations, formulas, graphs, etc. that I've spent so much time
developing.

Is that something that is relatively easy to accomplish with Excel? I'm not
a programmer, but have built some pretty impressive Acess database
applications and even sold run-time versions of those applications in the
past. I'm wondering if there's something comparable in Excel.

Thanks,
Ralph
