One of the best PS tutorials I've seen. Thanks!

Follow this series! PowerShell is new to me ... have watched many and tried to absorb ( it has to be said ... not very successfully) but your tutorials are some of the best! Both in style and content. I have re-watched each of them and working along with them ... excellent! Highly recommended! - 76 year old of dubious intellectual stature.

It's funny how this youtuber has only 30 subs and explain better than majority! While some pathetics others puts advertising + merchandise + etc. Teaches you nothing!! Keep this channel growing! Never give up!

Niklas - problemet $csv | ForEach-Object { $pop[$_.Name] = $_.CENSUS2010POP} produces an error in PowerShell 7.3.4:- InvalidOperation: Line | 2 | $pop[$_.Name] = $_.CENSUS2010POP | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Cannot index into a null array. It works correctly in PowerShell 5.1 ...... Thanks for this excellent PowerShell series

That's funny, I tested this using PowerShell 7.something. I hope the video is still useful to you even with that error!

Eight months late, but I finally realized what caused this. You need to initialize $pop to an empty hashtable before executing the above statement. Otherwise the expression $pop[$_.Name] will fail because $pop is null.
