scc 68 analog trigger with analog out

[CameronC]

Hello, I am very new to Labview, and I am struggling to grasp this software. I have a PCI-6036E and an SCC 68. I am trying to abtain an AI from a pressure sensor, and once that value reaches a certain level, a certain time delay, and then I would like the software to remove the voltage that is constantly being sent to the control side of a relay (to open the relay). I am struggling with the "Start Analog Edge" trigger. It is continuously popping up with an error stating that I have chosen analog input, but i can choose digital...

Is this a limit due to the hardware we have in our lab?

If this isn't. How can I achieve my goal.

As I stated, this is new to me. And before referring me to examples, I have looked at a few that I feel are helpful (cont acq sample-timed loop-analog start) , but these present the same trigger error. 

Thanks in advance!

Your problem has nothing to do with LabVIEW. Have you looked at the specs for the card? You only have a digital trigger. You can acquire without a trigger and check to see of any value is greater than your threshold.
