Update of tables via subform

[isetea]

I have a form, which has text fields where user can enter data freely. The field values should be stored in tables. Therefore I created a query which selects all fields of all tables which have to be updated by the user and every test field in the subform relates to the field in the query. But now the fields are locked somehow as I can't update the fields neither in the query nor in the subform and therefore can't update the tables.

What possibilities do I have to get a table update via subform?

I hope there is somebody who can give me a quick answer.

Thanks very much
