PowerShell / Excel SplitRow Code Debug

Can anyone figure out why this code is not creating a split-row on EACH worksheet?

Here is what I've got:

# Open Excel document

$ExcelDocument = New-Object -comobject Excel.Application

# Name the Excel document using seconds for testing at this point

$ExcelPath = "C:\ServerAudit_"+([datetime]::Now).tostring("yyyyMMddhhmmss")+".xlsx"

#Show the Excel Documents?
$ExcelDocument.visible = $True

#Display those pesky alerts?
$ExcelDocument.DisplayAlerts = $False

#Create a new Excel Document (aka WorkBook)
$Workbook = $ExcelDocument.Workbooks.Add()

#Create worksheet tabs for each server, since Excel starts with three, add tabs if we have more than three servers.

If ($b.count -le 3) {for ($j=1; $j -le ($b.count-3); $j++) {$Sheet = $Workbook.WorkSheets.add()}}

# Determine Number of Servers

$limit = $b.Count

# Write the Excel sheet tab names
							
For ($j=1; $j -le $limit; $j++)
{
    Write-Host "Creating worksheet tab for ";$ServerList[$j]
    $CurrentSheet = $Workbook.WorkSheets.Item($j)
    $CurrentSheet.name = $ServerList[$j]
    $CurrentSheet.application.activewindow.splitcolumn = 0
    #Where we want to split the screen for scrolling in Excel
    $CurrentSheet.application.activewindow.splitrow = 16
    $CurrentSheet.application.activewindow.freezepanes = $true
}

Select all Open in new window

Unfortunately, this works for the FIRST worksheet, and then all of the other worksheets do get the split-row functionality.... what am I missing?

Thanks All
