I want to reflect the number of entries in a multi-variable set in variables other than the variable set.

[M_Tomy]

I am a beginner in development.
Please tell me.

I want to reflect the number of entries in a multi-variable set in variables other than the variable set.

(For example) 
I want to store the number of records in a multiple variable set of catalog items as a total number in other variable sets and display it on the screen.

P.S.
 I am not a native English speaker, so please forgive me if my question is difficult to understand.

Dear Ankur.

Thank you for your prompt reply.
My English was not good enough and the completed image I wanted to convey was different.

Once again, my question is as follows.
I would like to store the number of records in a multivariable set in a separate variable as shown in the figure below.

Please let me know if you have any suitable knowledge.

Dear Ankur

I am sorry for the time and trouble I have caused you.
I will try to read and understand the knowledge with the members who are developing with me, and then try it in the development environment.

Please give me some time to reply as I will be away from tomorrow until Friday for training.
