David,

Thanks for your quick reply.

I am not depending on the messagebox to monitor what is going on. I inserted that code defensively in cases when i wasn't running this under the debugger. With the debugger, I am actually displaying the value contained in the SEEK argument in the Watch window.

In answer to your other question: the treeview key value is the value of the LOCID + '_', and I am monitoring that in the watch window, as well as val(THISFORM.NodeX.Key) to confirm that it is returning the correct LocID.

The thing that is odd here is that the SEEK() works correctly the first time, but not the second time. It returns .T., but sets the record pointer to record #1.

Again, note that LocID is an integer, not string. The seek shouldn't be confused by things like spaces or extra decimal places.

I have tried deleting the CDX file, and then recreating it. That didn't fix anything.

Jim
