How to reset counter with each iteration and how to introduce a delay

Hi everyone,

First I apologize for the basic level of my questions, I am very new with Labview...

I am reading counts off of a USB-6008 labview chip using the DAQ assistant and I write the output to a file. The problem is that instead of giving me the number of counts for each iteration it gives me the sum of it all. How do I make the DAQ assistant reset to 0 counts on every iteration? I tried using a shift register but it just adds a counter to my file and nothing else...

Thanks a lot
