We typically do not use the Bottom Nailer in our Base Cabinets. But in situations where we remove the bottom and run the back to the floor, I want this to be added.

I changed the Bottom Nailer Prompt prompt to:  =IF(Remove_Bottom=1,Use_Bottom_Nailer,0) but it doesn't seem to be working. 

Also, If I use a Thick Back, I don't want the Bottom Nailer to be used at all, so how would that formula look?
