Query regarding how to write nested for loop in robot framework by using keywords

[Nandini Muthina]

As my dev version is robot 3.1 , it is not supporting robot framework nested loops. So i need to  write a new keyword which implements a for loop and call that keyword inside of first for loop.
I tried but unable to get the logic.

This example should help.  Since robot 3.1 doesn't support nested loops you have to call a keyword to perform the inner loop.
