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

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.
