Determine if a cell value is within upper and lower bounds?

Hi guys,

This should be an easy one, but it isn't working in Excel for me.

I basically want to do this formula:

IF((Setpoint-0.6) <= Result <= (Setpoint+0.6), "OK", "FAIL")

It does not work because of how Excel treats comparisons. I've tried doing something like IF(Result => (Setpoint-0.6) AND Result <= (Setpoint+0.6), "OK, "FAIL") but it just gives me a #NAME? error.

Any way of doing this?
