SQL question

Hi,
     I have two files. The primary has an alpha field 21 characters long.
Positions 1 - 15 are the item number & 16 - 21 are a customer number. I
have to bring in info from this file and the item master, and sort on an
item master field. I tried the following SQL, but I get no hits. If I take
out the item master(IIM) stuff and print the fields item & cust, they look
OK. Can I do this? What am I doing wrong?

0042.00 C/EXEC SQL DECLARE A CURSOR FOR
0043.00 C+    SELECT  PRKEY,IDESC,
0044.00 C+        SUBSTR(PRKEY,1,15) as ITEM,
0045.00 C+        SUBSTR(PRKEY,16,6) as cust,PMETH
0046.00 C+      FROM ESP, IIM
0047.00 C+      WHERE PMETH = 'A'
0048.00 C+        AND :CUST IN ('      ', '770440')
0049.00 C+        AND :ITEM = IPROD
0050.00 C+      ORDER BY prkey
0051.00 C/END-EXEC
0052.00 C/EXEC SQL
0053.00 C+    OPEN A
0054.00 C/END-EXEC

And then in a DO loop

0074.00 C/EXEC SQL
0075.00 C+ FETCH NEXT FROM A INTO :PRKEY, :idesc, :item, :cust
0076.00 C/END-EXEC
