Hi all

I have this form with a cbo. This cbo is allowed to remain empty. If the user moves forward without modifying then alls well.

Now supposing the user makes a selection and then he doesn't want it, how can he undo his selection. This cbo is connected to a lookup master database, as soon as the selection is made the FK in this table is updated with the PK from the lookup master.

Except reverting changes is there any solution. Please advise.
