ready to pull my hair out final SQL question of the day

after this I am going to go home, throw the phone out the back door, fill 
the ice bucket with ice, grab a tumbler and a bottle of single malt and park 
my carcus on the sofa and not move for the rest of the day......

I started expanding my select statement, which includes a calculated field :

sum(ilneprice) - sum(ilneuavcst) as margin

I have declared a variable dmargin as a type S length of 8 with two 
decimals.....so far so good....

In my fetch statement I have the following:


C/EXEC SQL                                                             
C+ FETCH DETAILCURSOR                                                  
C+ INTO :ALPHA, :CUSTNO, :DNAME, :STKNO, :DESC, :PRICE, :COST, :DMARGIN
C/END-EXEC

When I go to compile the sql precompiler balks and tells me that the 
variable DMARGIN is not defined or usable.....nothing else.

Its declared properly and everything else seems to work.  I checked the 
order of the select fields and that is ok as well.

I would post the relevant code but I did not want the message to be too long.

Ideas?
