Excel has such fancy programming features that you can probably get it to eliminate the ones that you code as "RB" (Rainbow Bridge) or that have a date of death, when you are doing other calculations.
I am not very adept at Excel, because I've never spent the time on it, but I have a background in programming and I never like to do anything by hand that can be automated.... lazy me! (of course it's always a big job to get a program working right)
... Oh yes, another question. How did you capture the Excel page to put it in your message? Is there a way to capture any Windows page?
