So I’ve had a chance to try your suggestions and am having some issues. My main issue right now is that the count I’m getting from CountFields is unreliable. The playback server has 519 clips in it and I get a different clip count every time I run it. For now, I am just testing CountFields as a command and not an ack command so that I can see what is going on. The other curious thing is that using ioresult in CountFields does not work for me. I have to declare a variable using the Received device variable. Any thoughts?
