Need powershell help!!

Hello Everyone,

I am new here, and I am struggling with powershell class.

I have 3 challenges that I am currently working on, in preparation for a test.

1. Script that display name and size of just the files in C:\Windows, formatted in a table, where # represents 1KB.

this is what i have so far, however I cannot get the "#" to show up in ascending order.

##############

clear-host

Get-childitem c:\Windows | format-table @{E="Pschildname"; L="NAME OF FILES"; A="right"},

                           @{E={"#" * ($_.workingset/1KB)}; L="SIZE(KB)"; a="left"; f="n0"}  -AutoSize

##############

any help would be greatly appreciated guys, been trying to figure this out for days now.
