[AccessD] Checking for Records in Recordsets

I had similar questions on the code logic / syntax, but I figured I was only seeing part of the deal and there might be good / other reasons for the choice of code.
But it did seem a bit odd prima facie.

Regards
Darryl.

A question: why are you setting Me.recordset = rstTemp?

Personally I don't see how rstTemp.EOF I'd giving an error when the Set statement just prior to that does not.

I could see if the Set statement was failing how the assignment might not replace the prior existing definition of rstTemp, as happens when setting other objects equal to something undefined will do (I think).

Anyway, no help here, sorry, just questions!
