Invalid Identifier error

Hi All,

I have created a parameter using manage parameter option form edit queries. But I want to call that parameter in a measure, so I created a blank query and I am trying write this syntax 


As you can see I have named my parameter on right hand side as "Select Measure"
so when I write a syntax in blank query like this 
let
Source = #table({“MeasureParameter”},{{#”Select Measure”}})
in
Source

It gives me Invalid Identifier error. over this section 

I have no idea what is happeneing, My actual parameter is on right side of syntax, so what is first part which I have highlighted?
I think its just a random name by which that parameter will be called.. I need help on this..

I am following this article

Thanks in advance.
