Delete subform records without deleting main form records

I have a data-entry main form with several embedded subforms for entering
contact info.

My main form has information on the Entity (usually a company). It is joined
to the subforms by Entity ID.

Because of the way my Contact table is structured, each piece of contact
info -- such as name, address, email, phone, cell phone, etc. -- is contained
in a separate record. I have separate subforms for entering each type of
info. The Contact subforms are bound to a join table called
Entity_Contact_Join and joined to the main form by Entity ID.

If someone presses the Delete key from within one of the subforms, I want
Access to delete the corresponding record in the Entity_Contact_Join table.

I attempted the following code on the Form_Delete event for one of the
subforms. It executes without error, but after it's done, all heck breaks
loose. I get a series of about 10 cascading error messages: "operation not
supported in transactions."

Is there a better way to go about this?
