Hi @rit372002,
You are getting error because you just copy pasted the code and when you do so the double quote will be different than the actual one. You need to replace all the instance of that. Best is copy paste in notepad and replace the opening double quote.
Select the opening double quote and press Cntl+H and enter the double quote.
Select the closing double quote and press Cntl+H and enter the double quote.
Or alternatively you can use the pbix file shared by Melisa.
Sorry for not uploading the pbix file as I am using my office system.
Thanks
Mukesh
