Power Query - Expression.Error Column wasn't found

[borkybork]

Hi! I've created a query that is dynamically linked to pull data from the most current version of the source file. I don't need to show rows 1 - 3, but I get an error that the column can't be found when I promote row 4 to headers. I removed top 2 rows, then used first row as headers. Not sure where I went wrong or what's causing the error. Could someone please help me fix this? Thank you in advance!

Source File: Data Sample.xlsx

Query let me update to the new source file Data Sample - Copy if I didn't make row 4 my headers.

Query gives me an error after cleaning up the report in PQ.

Carefully checking the column name and ensuring it matches the actual data source, you should be able to resolve the "Column wasn't found" error in Power Query. I

Did you at some point promote the first row to headers? This will often mess with the column names in unexpected ways. You may also be able to solve it by removing unnecessary "Change type" actions.
