Top Ranked Function in Narrative

Hi all, I am trying to get top 3 customers by revenue using top ranked function in narrative, however it shows error that “unknow symbol in expression: index”. Any thoughts?

Hi @Rachel1,
Are you able to share more about the Top3_customers? Is this a ‘Top Ranked’ computation? Maybe try replacing [index] with [0] or [1], so you can see if it needs a specific index number?

Hi @bergqdou , thanks for your quick response. You are right - I need to fill in [index] to get TOP N customers.
