cannot find printer file defined field

I have an F spec declared in a test program that I need to bind a service 
program to and may have things out of order.

When I attempt to create the module I get a SL 30 error telling me that it 
cannot find field PRTTXTAMT yet it is defined within the printer file 
appropriately.

Here is a part of the RPG source:
 FAPCHKPRTF O    E             PRINTER OFLIND(*IN99) 
 DCVTNBRTOWORDS    PR           200

 Dmystring         s             75                  
 Dmydec            S              2  2               
 Dmycents          s              2s 0               
 Dmycentstring     s             10a                 


Do I need to move the F spec below the prototype declaration?



If you bought it, it was hauled by a truck - somewhere, sometime.
