You would then enter something like =10^-5*B3^2 Notice that you need to explicitly state the multiplication operator, *. In a math text, putting 2 symbols next to each other, or next to a parenthesis as in your example, implies multiplication. Excel needs for you to spell it out. You also need the = sign to warn Excel that you are entering a formula. Normally, powers of ten are entered as something like 1E-5, but 10^-5 works just as well, just a little harder for these old FORTRAN trained eyes to read --McD _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
