Kevin,

Just use add parameters with range. In your other thread I posted code that does exactly that - receives parameters collection.

>Ok, here's the problem. If I code each param individually using native ADO code, I get a data set back. If I use this code above, I get no records. I have walked it through a few times and I cannot see what the problem is. The data being set on the oParam object all appear to be ok.

If it's not broken, fix it until it is.
