Question : Access: 'Control can't be edited - bound to unknown field'

I have an Access DB that has a field HasSnt in the Client Table.  It is set up as yes/no and matches the other fields in the table.

In the client form, there is a checkbox that should tie to this field.  However, it will not allow a person to check the box while using the form.  The message below is 'Control can't be edited - bound to unknown field HasSnt' (I had typed the field name under properies)

When I go into to alter the properies of the checkbox, it doesn't give an option to select HasSnt. It is not in the list

This did work on one of the earlier versions of this file.  Not sure why it would have stopped working.  

Answer : Access: 'Control can't be edited - bound to unknown field'

did you save/close the table?
close all open objects

do a compact and repair
tools> database utilities > compact and repair database

now open table in design view and see if the field you added is shown.
close the table design view

open form in design view and see if the field is included in the drop down..


btw, what is the record Source of the form? table or query?
if query, make sure that the field is added to the query fields selections.
