Reports :: Report Thinks Calculated Field Is Text

I'm creating a report to check for over- or under-stocked items. The report is working fine, gets all the records etc. except that it thinks that the OnHand field from my inventory query is text or something, at any rate not a number. I have successfully set the format of the field in the query to General Number, but that doesn't seem to have worked. Here's the SQL for the report:

Code:
SELECT DISTINCT Signs.SignCode, Signs.SignDescr, Size2.XYdim, qryOnHand.OnHand, Bins.Rack, Bins.Level, Bins.BinNum
FROM (Size2 INNER JOIN (Signs INNER JOIN (Items INNER JOIN qryOnHand ON Items.[ItemsID] = qryOnHand.[ItemsID]) ON Signs.[SignID] = Items.[SignID]) ON Size2.[SizeID] = Items.[SizeID]) INNER JOIN (Bins INNER JOIN InventoryDetail ON Bins.[BinID] = InventoryDetail.[BinID]) ON Items.[ItemsID] = InventoryDetail.[ItemsID]
WHERE (((qryOnHand.OnHand)<=[Check for signs with fewer than:]));
