Access 03

I have a sales quote form with line item numbers. I have a macro that
increments the item number (using dcount) when a new item is added. It's tied
to the After Insert event of the form.

When the macro runs, it leaves the record unsaved when it's done. If I
attempt to add a SaveRecord line, an error results that tells me I can't use
the BeforeUpdate event (which is maddening, because I'm not using it).

I don't like leaving the record unsaved, because the user my click the save
record button twice.
