I'm confused--if a control's Locked property is set to Yes, or the Enabled
property is set to No, you will not be permitted to change the data in them.
They should be set to No and Yes, respectively to permit changes.
However, certain queries are not updatable in and of themselves for a
variety of reasons. You can search this forum and or Google for conditions
that can cause this. Open your form's query on its own, and see if you can
change a record. If you can, then you will have to check the form and
control properties to see what's preventing changes. See the form's
AllowEdits, AllowDeletions, and AllowAdditions properties, as well as the
Data properties of each control.
Hope that helps.
