Changes not committing

[AlastairOz]

On my form I have a drop down list.
To add items to the list, I have a command button that opens another little form to edit the list.
When I open this form with the command button on the main form and make changes to the list, changes are not being committed to the table.

When I open the list by itself it works fine.

Oh, Never mind,
I found the answer, the default data session for the list form was set to default, needed to be set to Private..
