Analog triggered counter

Hello,

I am attempting to use analog edge detection to increment a counter, which I will then read from at a regular interval. I keep hitting brick walls when trying to run/adapt the examples on NI's site. 

I'm using a cDAQ-9174 chassis and a NI9223 analog input card with LabVIEW 2014 SP1. 

Any suggestions would be greatly appreciated. 

Thanks,

Emach
