I want my Driveworks Express rule to enter a parametric value in the custom property "Description" of my part.  My rule driving this property is basically:

=IF(randomvariable=true,"no value","User text "D1@sketch2@filename.SLDPRT"")

the bold section of the above rule is where my rule fails - I think it has trouble with the double quotations.  Is there a way around this?
