Vista - request for help

Below is a script that I am developing to pull all the computer objects out
of the Computers OU loop thru them executing a wmi query to pull the Model of
the computer. If i do this manually it works so I must have some logic issue
lurking here that I just dont get. I am rather new a powershell.....scripting
in general so be kind :-)
