I'm trying to get the dropdownlist to contain "1pt", "2pt", etc rather than "1", "2", .....

 

I tried using the FontSizesList which does display them properly in the dropdownlist but when I try to use them nothing happens. 

 

It looks like the strings from this list are being converted to integers and because I've added the "pt" it craps out.  If this is the case is there a work-around I can use?
