Setting up Parameter in Query on Power BI desktop

Hey, I am trying to create a Client parameter in my dataset, that when you change the client name on the parameter, all the tables update to only have the data for that client.  I created a server parameter and a client parameter. so P_Server & P_Client. Below is the query. This is actually using server views rather than tables, so not sure if that matters.   

(I made a post already, but it was marked as spam, so not even sure if actually posted. )

let
Source = Sql.Database(""&P_Server&"", "DW_Target", [Query="select *#(lf)from Table.Table#(lf)WHERE [Client]="&P_Client&""])

in
Source

However I keep getting the following error:

DataSource.Error: Microsoft SQL: Incorrect syntax near the keyword 'from'.
Details:
Message=Incorrect syntax near the keyword 'from'.
