Selection from Value List

Is it possible to select a field entry from a value list and after this ONE selection the field does not allow any new entry. I want to use this selection in a primary key and this selection should not change anymore since this is used in related tables.

Would appreciate any advice.

Best regards.

Sounds like a layout control issue.

Hide Status Bar [Lock]

Create

Next Record, Previous Record, First Record, Last Record buttons

each contains

If(isempty(YourField)

Goto Layout You can change this field

Else

Goto Layout[You cannot change this field]

Specify feild format, Allow Access off.
