Comma Seperated List in Narrative

I am trying to create a comma separated list in an insight.

An example of the default narrative for top 3 states by population:

  • California – 39 million
  • Texas – 29 million
  • Florida – 22 million

An example of the desired outcome:
California – 39 million, Texas – 29 million, Florida – 22 million.

I’ve gotten close by simply adding a ', ’ to the end of my list of values, but this tags a ', ’ at the end of list.

Hoping for help to remove that last comma.

Can you add a final if statement to check if it’s 3?

IF state.itemsCount !=3 -> ,
