My company makes modular tilt up wall panels. Typicall they are 4' wide unless noted otherwise. I've trying to make a wall tag that shows the Panel Mark and the width. The key thing is that if the panel is 4', i don't want the width to show up. I'm trying to set a visibility parameter (YES/NO if(Width<48") but can't seem to get the formula to recognize the Catergory Parameter for Width. Any advice? Thanks

Yes/No parameters are a little funny, they seem to assume that the formula is an 'if' statement. Try just entering *Width > 48"* (no asterisks). If the formula is true the parameter will be checked, if false, unchecked.

You're right, I was trying to insert the statement incorrectly. I corrected this but its still staying "not a valid family parameter". I'm trying to link the statement to a Category Parameter and not a family parameter.
