Hi Jason

I have read the help somewhat carefully. Thanks you are right I needed
to ! I think I now have a better grasp over what is happening, my trap
was that I was using explicit transactions in a number of places and the
Started property showed as true while they were running. However in one
piece of code it did not and this crashed with a parameter missing
error. The error stopped when I set Started := True. So I thought it
mysterious :)

However when I say my code, I actually mean a co workers code. So there
is probably some other issue causing the problem. Thanks for your time.
