Try the following array formula...

=SUM(IF(ISNUMBER(A1:G13),A1:G13*1.2))

....confirmed with CONTROL+SHIFT+ENTER.

Hope this helps!

How can I find all cells in a sheet that are a number
greater than zero and multiply each one by a number?
IE: the number to multiply by is 1.2
A1 Tom
A2 25
A3 0
G12 Bob
G13 25

I want to programatically (without using a macro) find
cells a2 and g13 only and multiply them by 1.2

Thanks in advance for your help.
