Updating A Record Using 2 Tables

[maviko]

I have one table (call it tblMax) which holds a number designating a maximum amount for items. I have a second table (call it tblItem) which holds the items current inventory, along with several other values about the item. Is there a way to reference fields from both of these tables on one form, AND have the record be able to update? I've used a query to bring them all to one form, but the record is not able to update using that method. The tblMax will be used for reference only, after the initial values are entered. I also tried leaving the form's Control Source blank and typing in Control Sources for each field, but was unable to get that to work. TIA.

Make sure that both tables have unique primary keys defined.
Make sure that the query does not contain any aggregate functions.

If that doesn't help, post the SQL.
