Digital Logic - How to set the counter so that it only stays at its current value or increases by 1?

I'm working on a problem that requires me to count the number of times something succeeds or fails. However, with my current circuit configuration, I ran into the problem where it would decrease the other counter, if one increased. I am trying to make the counter increase by 1, or stay at it's current value if it cannot increase.

Here is my attempt at the problem. The software I used is Logisim.

There's a part two to this question that requires me to prevent further inputs into the system once the system is unsuccessful, which I have no idea how to implement.

It's not clear to me what signal in your diagram is a successful count and what is a failed count(?).

What are the two little boxes to the right of the flip-flops?
