Issue with System.Windows.Forms.ListViewItem / NullReferenceException - powershell

Question

I am getting the following error when I try to get a Listview of Applications in Powershell
Exception calling "Add" with "1" argument(s): "Object reference not set to an instance of an object."
At D:\scripts\AWSA.ps1:527 char:79
+ ... ?{$_.Index -ne 0})){$Field = $Col.Text;$Item.SubItems.Add($_.$Field)}
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : NullReferenceException
The code that is rendering the result is
...
$btnApplications = New-Object System.Windows.Forms.Button
$lvMain = New-Object System.Windows.Forms.ListView
...
$btnApplications_Click={
Get-ComputerName
Initialize-Listview
$SBPStatus.Text = "Retrieving Applications..."
Update-ContextMenu (Get-Variable cmsApp*)
$XML.Options.Applications.Property | %{Add-Column $_}
Resize-Columns
$Col0 = $lvMain.Columns[0].Text
$Info = Get-WmiObject win32_Product -ComputerName $ComputerName -ErrorVariable SysError | Sort Name,Vendor
Start-Sleep -m 250
if($SysError){$SBPStatus.Text = "[$ComputerName] $SysError"}
else{
$Info | %{
$Item = New-Object System.Windows.Forms.ListViewItem($_.$Col0)
ForEach ($Col in ($lvMain.Columns | ?{$_.Index -ne 0})){$Field = $Col.Text;$Item.SubItems.Add($_.$Field)}
$lvMain.Items.Add($Item)
}
$SBPStatus.Text = "Ready"
}
}
Do I need to add a null variable such as if($SubItem -ne $null){$Item.SubItems.Add($SubItem)} ?
