do not try using full columns ( as in E:E) with SUMPRODUCT

Bernard,
As far as I can tell the formula works great. I am just not sure what it is
telling me. I am getting several different solutions to the formula. Can you
translate?
Thanks,
Steve

Let A1 hold: "this . is a dot" - no quotes, of course
Let B1 hold formula =SUBSTITUTE(A1,".","")
B1 will display "this is a dot" --- i.e. the period is removed
any help?
