%subst problem

["Phil Kestenbaum" <pkestenbaum@xxxxxxxxxxx>]

This statement is blowing up. However during a debug, I have values in
both nStartPos anf nEndPos and they appear to be correct, 30 and 39,

This is where we get an invoice number. J8_Comment has contents and they
are what they should be. I am not sure what is wrong at this point.

 

eval      J8_Comment  = %subst(J8_Comment : nStartPos 

                        nEndPos)                      

 

 

Yet I am getting this fatal error:
