Using ASTM Function in Component Table

Hi Kirk

I'm using this coding as a data expression that is part of a component table, so it can print as part of the material description.  

<<ASTM_Name(_
<<SV READINGS.Reading>>,_
<<SV READINGS.Percent_Finer>>,_
<<ATTERBERG.Plastic_Limit>>,_
<<ATTERBERG.Liquid_Limit>>,_
<<ATTERBERG.Organic>>_
)>>

Should work right?  It is not.  No group name is printing even though I have data in the referenced fields.  There's no issue with using this within a library component table, is there?
