I think (I might be wrong) that when the UNLOAD event occurs, your table is already closed.
Maybe you can create a property in your form (say lcLastName) and in the QueryUnLoad event: ThisForm.lcLastName = ThisForm.lstLookUp.Value.

You can then in the UnLoad Event: Return Thisform.lcLastName

I hope I'm right or at least point you in the right direction...
