I have a combo box where the user selects a client from a list. The users like to type in the first letter and then select the client. I made some necessary changes to the underlying query for the combobox row source (whether the client has a balance due and whether the client is active - they need to be able to see all clients but also know their statuses). Since then, when they type in the first letter, an error pop up says "Field cannot be updated", but once you click okay, you can continue typing and it saves as usual. I just need to find a way to get rid of this pop up. It only happens on new records, so I thought about making a dummy record that says "Select client..." but I'd rather know what the actual problem is than just put a quick fix on it. Any thoughts?
