Thanks for your replies,

The structure: InvMast is the Master table with the description, part number, stock re-order level, etc. InvOnHand is a table with only the part number, and the quantity on hand.
In the InvOnHand table it creates a record for each part number in each location(ie.--if part 011 has 2500 in location 01 and 32 in location 02 then there will be 2 records, if however there is 3200 in location 02 and 0 in location 01 there will be only 1 record for the location that has something on hand).

Thus, I can assume that when there is no record in the onhand table, that part number has 0 on hand in that location. My question is: How do I test for this within the SQL statement?

Here again is the statement I have thus far:
SELECT INMAST.FPARTNO, INONHD.FONHND ;
	FROM INONHD RIGHT JOIN INMAST;
	ON INONHD.FPARTNO=INMAST.FPARTNO;
	WHERE &LCWHERE;
	INTO CURSOR TMP1
LCWHERE is concatenated according to other conditions within the form...is there a way to put like an IIF() like this?
SELECT INMAST.FPARTNO,IIF(EMPTY(INONHD.FONHND),'0' AS FONHND,INONHD.FONHND)...
I've tried the above and it keeps giving me an error when the SQL is executed that it needs a )....got any ideas?
