Adding PowerShell Script to Primalform

I am trying to add a PowerShell script into a PrimalForm GUI and seem to be having difficulty getting it work. The script allows you to update Active Directory description on multiple machines listed on a .CSV file. Below is the script I am trying to add:

 <#Update computer description
Open notepad and create a .CSV file. Add ComputerName,Description as the headers.
Below the headers type each computer name and description separated by a comma.
EXAMPLE:
ComputerName,Description
HORMEDTKWK40797,Test_Description
HORMEDTKTB47144,Test_Description
#>
Import-Csv "C:\scripts\computerdescription.csv" | % {
$computer = $_.computername
$Desc = $_.Description
set-ADComputer $computer -Description $Desc
}

Below is the Primalform GUI format. The GUI gives you three options: Update a localhost AD Description, type a computer name on the form or browse to a .CSV file. Thanks!
