Bob,

There was a thread on VARTYPE() in combination with objects a few months back.

You will get the expected result as long as the object actually exists, but you will get an error reported if it does not. At least that's how I remember it as going.

I believe the the upshot of the thing was to steer clear of VARTYPE where objects may be concerned.

Cheers,
