Trying to modify two AD User attributes for multiple users?

Question

Hello,
I'm a newbie to Powershell and need some help.
I have a 2008 R2 AD and need to modify two attributes for multiple users.
The attributes include "homeDirectory" and "unixhomedirectory".
I have started to go through Powershell in a month of lunches but need this solution quickly.
I have been trying  number of scripts that I cannot get to work in our test AD lab.
Is there anyone who can help with a simple script with explanations of each line so I know how it works please?
help

Thanks clayman2,
Here is what's in my .csv below
samaccountName
homdedirectory
unixhomedirectory
testuser1
\\servername\oldhimedir\%username%
\\servername\oldhimedir\%username%
testuser2
\\servername\oldhimedir\%username%
\\servername\oldhimedir\%username%
This is the code below I'm trying to use.
Import-Module ActiveDirectory
$USERS = Import-CSV c:\users.csv
$USERS|Foreach{Set-ADUSer -Identity $_.samaccountname -homdedirectory $_.\\servername\oldhimedir\%username% -unixhomedirectory $_.\\servername\oldhimedir\%username%}
Please let me know if I have to put the pathing in any special brackets to have PS read it. I have tried {} around the field but I get "Missing property name after reference operator"
Thank you
