200565 error

I'm trying to write a sequence of signals to a port on my USB-6343. Two of the signals are fixed and the other is an array of binary values. I am not getting any output on the DAQ port pins (port0:line0:7) and I'm getting the error 200565 when the loop ends and the Clear Task module is executed. I can't figure out why either are occuring.

This is my first foray into programming DAQ's with LabView so this could be simple.
