Is the counting combinator broken? I connect the input of a decider combinator to a belt with condition: "each" > "0"; output: "each" with a value of 1. I then connect that decider output to a counting combinator with reset at "-1" and I receive no ouput. In fact, I haven't been able to get the counting combinator to output at all no matter what the rest number is set to. Am I doing something wrong or is something not functioning correctly?

Tested and it's not broken.
Set output to the +1 signal from UC and set it to input count or 1
Set belt to read and pulse
Connect belt to decider input
Connect decider output to counter
The counter will out put a signal called "count"
The key is to have the belt pulse not hold

Thank you for the help, I'll attempt to get it working based off this. Cheers!

Glad to help!
Have fun!
