I am trying to control a Yes/No parameter by having it reference another parameter. Hoping someone can give me insight into what the correct formatting should be for the formula.

Example:

Void D TR = 2'-0"
Check Box Parameter (yes/no) = IF(Void D TR>0', "Yes", "No")

I can get this formatting/formula to work in a "regular" parameter formula but I am having trouble in the Yes/No area.

Can anyone lend a helping hand?
