That will tell it "If they put in something greater than Panel Width, just use panel width instead. Otherwise use the value they gave you."
But, i would make the panel symbol in plan USE Panel Width, and then CONSTRAIN it with another dimension. That way when the doors change size, the panels and the panel symbology are the same. (Maybe thats what youre doing?) I suppose in either case you would want the formula for the opening amount...
