IF statements in general tables

Newbee here.  I am trying to use an IF statement in a general table in a drawing.  I am using a custom property to extract a variable from a part file.  The value of the variable is either a 0 or a 1.  I am trying to get the if statement to interpret that value as either a yes or no.  IF ('value' = "1"; 1; 0).  The equation always comes back with a true value - "1".  If I go into the part file and make the variable a "0" value the IF statement does not change.  The custome variable in my drawing file changes to match what is in the part file.

Any clues?

Any help is greatly appreciated.
