I thought I was finally getting the hang of the newly rigorous SQL syntax - but I cannot figure out why VFP is complaining about this:

SELECT Category + STR(wmretail,8,2) AS IndexMe, SUM(Shipped) AS Shipped, ;
	SUM(ShippedYTD) AS ShippedYTD, SUM(Return) AS Return, ;
	SUM(ReturnYTD) AS ReturnYTD, SUM(Sold) AS Sold, ;
	SUM(SoldYTD) AS SoldYTD ;
	FROM WalDataFile ;
	GROUP BY Category + STR(wmretail,8,2) ;
	INTO CURSOR PricePtSum

???
TIA
