Hello,
Thank you for your efforts to understand my problem, but I think that neither fjames nor Eugene have, by my fault, understood what exactly I meant. I will try, along the lines of the explanation of fjames, to better clarify what I have done.
I took the CircuitA from Project1, I imported it ...

Thanks for the answer, but the problem is not in the circuit of my counter, he works well, as you can see in the attached sketch. The problem is, as I said, in the coexistence of the two counters in the same project. If, for example, you open the project containing the counter "Conta" and import ...

The "Conta" circuit is the one I created by modifying the original "Cnt" taken from the "Digital Clock" project.
In the same project the two counters can not coexist. When I insert one already containing the other, the latter changes.
I attached the two counters.
Thanks

Hi,
I'm a new user and I have a problem to solve.
I have created a new counter by modifying the counter "cnt" of the Digital Clock example in the program.
When I try to use it in a project in which I need both counters, I can not do it: in the circuit where the original counter should be present ...
