Creating if Parameters

I have been working on creating windows for the place I work.  I want to make my windows so they are quick and easy to create new ones without having to add in new information like if the glass is tempered or if its an egress window. I would like to set up formulas for these.  I am stuck at my egress window parameter.  I have included an image of what I am working on and the calculations and formulas I have so far.  I would like to have my egress check box to say yes if the Opening Width is greater then 20", the opening height is greater then 24" and the opening sf is greater then 5.7 Sf.  How would I set this parameter up?

You would want to make use of the AND function to return a single TRUE / FALSE result:

 

= and( Opening Width > 20", Opening Height > 24", Opening SF > 5.7 SF)

 

This formula will return TRUE only if all three of the conditions are also TRUE.

This worked like a charm! Thanks so much! I was close but didn't quite have the correct formula and was getting quite frusterated.

Just a question out of curiosity: Does the rule really say greater than, or it says at least, no less than?

 

Will these two openings meet the egress rule? If the rule says no less than 20" in Width and no less than 24" in Height, and no less than 5.70 SF in Area, these two openings would meet the rule, but your yes/no parameter will not turn On.
