Hi

Trying to use the below for a RS PCF but it errors, I cant work out what the error is, any ideas?

(((C-C63)/C63)*.4)+(((C-C126)/C126)*.2)+(((C-C189)/C189)*.2)+(((C-C252)/C252)*.2))*100

Cheers

The only thing I see off the bat is a missing parenthesis at the beginning.

((((C-C63)/C63)*.4)+(((C-C126)/C126)*.2)+(((C-C189)/C189)*.2)+(((C-C252)/C252)*.2))*100

Or maybe:

40 * C / C63 + 20 * C / C126 + 20 * C / C189 + 20 * C / C252 - 100

Thanks Bruce !

You're welcome.
