Sounds like it might be a split or main form/subform design
The record controls down below change the record ok
your recordset may be locked or uneditable. Is the form bound to a table or query? If query is the query editable if you open it?
but I can not type in the field
Don't create a form to create records then another one to edit the same records. Use the same form for both purposes.
I have created data entry forms no problem. I am now creating a form to modify the other fields in the table.
If you can post a zipped copy of the db it will answer a whole lot of questions.
The more we hear silence, the more we begin to think about our value in this universe.
