Ben,
Thanks for the reply. I had sent a response to Ben's reply earlier
today, but I guess it didn't go through.
I figured the order of execution was the issue. I was hoping for a
way to "trick" the execution order and tried writing the function call
in a bunch of different ways other than the example I provided, but no
dice. Ben posted a nice response, though looping with reFind() does
the job for now.
Thanks again,
Jon
