Expression.Error: We cannot apply operator & to types Text and Table

I am trying to combine two queries where results of one query will be consumed as parameter in other. To hook in results, I used & to combine strings. But while executing I'm getting error & cannot be applied to text and table. I tried several alternatives but none are working. Can someone please help me understand how to fix this?

 

My queries are something like this

let latestGA = Sql.Database("...."]) in latestGA,

query = Text.From(Text.From("let Events = reportdatav2 | where AppInfo_Version in ('") & @LatestGA & Text.From("') | extend payload = parse_json(GENERIC_PAYLOAD)")),

Data = Json.Document(Web.Contents("....",[Query=[#"csl"=@query,#"x-ms-app"="PowerQuery",#"properties"=.....)),

Need Help

    Hey shwethag 

     

    here you have a short ScreenGif that explains how to create "Parameter-Queries".

     

     

    Please create one parameter query by one.

     

    You are also writing the parameters wrong you don't need that @ you also have a syntactic error in the first line -> You don't need that braket -> May I refer you to this article Article_1, 

     

    If this post was helpful may I ask you to mark it as solution and give it some kudos?

    Have a nice day!

    BR,
