Weird Power Query Editor for PowerBI message - Token Comma Expected after "in"

[ANJnKW]

I am reaching out as I have wat I thingk is a weird error reponse, as Power Query Editor for Power BI is noted "Expression.SyntaxError: Token Comma expected."
But the feedback is noting it realted to the "in", which makes my head hurt.
It makes no sence to my little brain, and I have never has this problem before and my other Queries are find and dandy.

Any Thoughts, I know this is goign to be simple and I will feel foolish when someone says, "it is simplke and obvisous, it is because" . . . .
THANKS in Advance if you are willing or able to provide a comment!

Here is the feedback I am getting

Can you post the full query statement, not by image but using the M-code icon.

Something like

let
    step 1 = Table.something... ,
    step 2 = ...
in
step 2
