Hi Philip
Thank you so much for the response! I tried patching in that query into my original source and didn't get any syntax errors so that's good. However once it tried to run the query I get an error that states:
Expression.Error: The column 'Index.2' of the table wasn't found.
Details:
Index.2Here's the query after the space is the your query

Can you please send me the data you are using, and a screenshot of the table in Power Query before you add my query steps.
My query is using column names specific to the columns in the dummy data I set up. Your query is using column names that are in your data.
You need to replicate my steps to carry out the transformsations on your data/columns. The error you are getting is is because my dummy data has a column called Index.2, yours doesn't.
If I can see what data and column names you have, I can try to modify my code to match your column names.
Regards
Phil
