Jay --

What is it that you're putting in that spot where "the record is available temporarily"? I see the spot for it ... but what are you doing there?

And ... the code you're seeing there is what I've been using for a loooooooong time. Can you post just that block of code, so I can see exactly what you've implemented? Perhaps you've made an inadvertent change, or I eliminated something ... who knows?



>It does. Would you mind taking a look at my other post "Allowed DO nesting..." if you get a chance? I'm getting this error when I put stuff in the place where it says to put it when the record is available temporarily.
