Reset Analog MUX and/or Mathematical Equation to Zero

Hello folks

I can't figure out how to zero or reset output values via an input.  In my example, you will see that each time I5 is pressed, a value of 10 is added throughout the chain.  How would I use an input to reset the values to zero?  I can't figure it out.  Please note, the program I have submitted is just a copy paste from a larger program.  I only added this section as it demonstrates what I am trying to solve.

As always, any help is always appreciated

The circuit is an analog counter.
If you add a button to B094, the counter will be reset.

What's your problem?

 Would you please clarify your question?

ixo65

Please explain what the circuit is supposed to do and why you think the counter is not set to 0?

Where exactly is your problem?

Well, first of all, thanks for your help.  I really do appreciate it and I know that as a hobbiest I have ALOT to learn.

I suspect my problem is mostly that I am still learning :)  I am still trying to understand the And(edge) but I will get it over time.  Please see another cut and paste from my program.  You will see that I2 adds 10 and I1 resets the counter to zero as per your previous reply.

But if you look at NI17, 18, 20, 22 you will see that they add to the sequence while NI21 subtracts 5 and NI19 inhibits the analog output but does not reset the chain to zero.  i used the solution you provided to add an input to B104 to reset that sequence to zero but I can't see how to apply that same solution to the NI sequences.

Any thoughts?

 This is a challenge as I have been unable to get the sequence to reset from NI19 no matter what I do.

I have tested the program in simulation mode and it works.

 Interesting.  I can only get Ni19 to turn the output on and off.  For example - if it has an output of 25 and i turn it off and back on with NI19, i still get the output of 25.  I am trying to have output start at zero when i use NI19 to turn it back on.

 I very much appreciate your time and effort with this.  You are correct, the small program section I cut from my overall program works as intended on its own.  However, the original program in its entirety does not so I was able to determine that there were connections severed when I cut and pasted it out.  Several of these connections were preventing the NI chain from resetting to zero.  It took a while but I was able to figure it out and now its all good.  This has been an educational exercise
