Help please!

I need help with an equation.

I would like to would like to control the suppression of a feature based on a global variable. I have this so far but can not get it to work properly:

**NAME VALUE/EQUATION**

CUT-EXTRUDE4 =IF("DOORWIDTH">24.0625<29,"UNSUPPRESSED","SUPPRESSED")

CUT-EXTRUDE5 =IF("DOORWIDTH">29.0625<36,"UNSUPPRESSED","SUPPRESSED")

CUT-EXTRUDE6 =IF("DOORWIDTH">36.0625<48,"UNSUPPRESSED","SUPPRESSED")

As you can see as my door width variable changes I just wan't a certain feature suppressed or not. If my door is 32" I want CUT-EXTRUDE5 unsuppresed. I just dont think I have the equation written properly. Can someone help please with a greater than less than equation.

Thank you everyone for your help. I actually got it to work using the equation in the attached screen shot.

Thanks again.
