Parameter query? [Resolved]

[salvelinus]

I've got a parameter query based on one table. The field names in the query don't match the field names in the table.

DELETE [Main].Hospital AS Expr1, [Main].Hospital AS Expr2, [Main].[Hospital] AS Expr3
FROM Main
WHERE ((([Main].[Hospital])<>[Which Hospital?]));

Hospital isn't a field in Main. What's going on? The query apparently works when run in a DoCmd.OpenQuery statement.
