Help with PASS/FAIL function

Hi all,

I need a formula that determines if a value passes or fails. basically, if cell g21 is ±15% of cell b7, then it passes. if it is more than ±15%, then it fails. I am at a loss for where to start. please help.

thanks,

ias

Thanks, but that doesn't work. I find that if you replace the OR with an AND, it works. Thanks again.
