Modify code below

$_.'Post code'

to

$_["Post code"]

Full code:

At first glance, the following line is incorrect

$list.Items |  Get-Command | Where-Object ...

The Get-Command is incorrect and you are passing its output to Where-Object instead of $list.Items

Try this instead.

 $list.Items | Where-Object ...

Also i noticed that your spelling of Post Code in the Where-Object should be a capital c for Code
