Selection / Omission

I am trying to build a simple joined logical that must have a selection on 
two separate fields, but the compiler continues to burp at me, something 
about DYNSLT which I have never used in the past.  What I want to do is 
simply select ONLY those records that are equal to the TWO selection 
fields....nothing else and I am not sure what the compiler wants it to be 
dynamic.

Here is the source:

A          R TRAFFIC                   JFILE(IMPILN00 IMPIHD00)
A          J                           JOIN(IMPILN00 IMPIHD00) 
A                                      JFLD(ILNINV# IHDINV#)   
A            ILNINV#A           I      SST(ILNINV#A 1 1)       
A            ILNEPRICE                                         
A            ILNEUAVCST                                        
A            ILNINVDATE                                        
A            IHDDELIV                                          
A            ILNLNTYP                                          
A          K ILNINV#A                                          
A          K ILNINVDATE                                        
A          S IHDDELIV                  VALUES('999')           
A          S ILNLNTYP                  VALUES(0)               

Any help would be appreciated.

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