Then, as is it won't work for us. If it can be upgraded to integers we can try it.
Thanks for the info. Saved us some time in fruitless testing. Now that we understand what is going on, we're getting better results. We will still need to conduct more tests, but will report back to the list with the results. Michael On 8/2/07 5:31 PM, "Glynn Clements" <[EMAIL PROTECTED]> wrote: > > Michael Barton wrote: > >> 1.
