Execution Plan

Hi team,

I am having script with one main function and 2 sub functions that will fetch the table values, while am trying to execute in execution plan in main function got passed but it shows error in sub function as "can't read tBodies property of undefined" and also while in single script execution it will not throw any error.

I have attached image below, how I have created execution plan also, let me know If any other ways to do these into execution plan.
