hi Commcare people 
so I am trying to create some dashboards using PowerBI, I walked through steps taken from a previous post in this forum, I have created the Excel dashboard integration, copied the link, then in PowerBI created a new blank query, then using the advanced editor I copied :
let
Source = Web.Page(Binary.Buffer(Web.Contents(“Url”)))
in
Source
in URL I inserted mine so I think everything was going well, but I get the error in the image below:
can anyone please tell me what to do? or how to solve this?
thanks in advance
