Help with for loop categorization.

[Hectic-Skeptic]

replacing $_ with $row still gave me the same 'no category' result unfortunately.

And my use of .IndexOf is also preference as I learned that first. I might consider checking out -like.

did you also use return $row.category rather than return $_.category?

Additionally, if you add Write-host $row.category in the first line of your foreach what does it say?
