multiple groupboxs with autosize

Based on the needs of this little project, i have a small Powershell GUI that generates a Groupbox object for all my webservers.  Inside each server groupbox i generate a groupbox for each site, that contains 2 radio buttons, and a textbox (small control function).

 because the number of the sites on the servers can vary, i need to have the server groupbox autosize to contain all of the potential sites.  problem i am having is the first, second and third server group boxes generate with proper spacing between them.  The 4th one wants to segregate itself further away and i cannot figure out why.

i have attempted to put in some write-host points to see what it is doing.  i am attempting to use the .bottom point of the previous groupbox as a reference to start the next one.  as far as i can tell even though the autosized groupbox varies in size, it always shows the height of the box being only 100.  

Any ideas?

here is my code.

$servers @=(server1, server2, server3, server4)
$Y = 20
$X = 0
$h = 20
$b = 0
$cv = 0
$Yoffset = 0
foreach ($srv in $servers) {
	If ($cv -lt 2){
	 $X = 10
	 $Y += $Yoffset
	 } else {
	 $X = 300
	 $Y = 0
	 # $Yoffset = 0
	 }
	$srv
	$X
	$Y
	$Yoffset
		 New-variable -name "$srv" -value $(new-object System.Windows.Forms.GroupBox -Property @{
			 AutoSize = $true
			 Location = New-Object System.Drawing.Point ($X,($Y + $Yoffset))
			 Text = $srv
			 ForeColor = "Blue"
			 })
		 $Form.Controls.Add($(Get-Variable "$srv" -ValueOnly))
		 $srv
		 write-host "top:  " $(Get-Variable "$srv" -ValueOnly).Top
		 write-host "bottom:  " $(Get-Variable "$srv" -ValueOnly).Bottom
		 write-host "Height:  " $(Get-Variable "$srv" -ValueOnly).height
		 $Yoffset = $(Get-Variable "$srv" -ValueOnly).Bottom
		 if ($cv -eq 2){
		 $Yoffset = 20}

		 	 		 
		  $cDir = "\\"+$srv + $basepath
		  $exclude =@("aspnet_client","tinybox2")
		 $contents = Get-ChildItem -Path $cDir -Exclude $exclude | where {$_.PSIsContainer}
		 $i=20
			  foreach ($dir in $contents){
				 $dir.name
				 New-variable -name "$dir.name" -value $(new-object System.Windows.Forms.GroupBox -Property @{
					 Location = New-Object System.Drawing.Point (10,$i)
					 Autosize = $true
					 Size = New-Object System.Drawing.Size(250,50)					 
					  Text = $dir.name
					  })
				   $(Get-Variable "$srv" -ValueOnly).Controls.Add($(Get-Variable "$dir.name" -ValueOnly)) 
				  $rbN = New-object System.Windows.Forms.RadioButton
				  $rbN.Location = New-object System.Drawing.Size (10,15)
				  $rbN.Size = New-object System.Drawing.Size (40,25)
				  $rbN.Text = "On"
				  $(Get-Variable "$dir.name" -ValueOnly).Controls.Add($rbN)
				  $rbF = New-object System.Windows.Forms.RadioButton
				  $rbF.Location = New-object System.Drawing.Size (55,15)
				  $rbF.Size = New-object System.Drawing.Size (50,25)
				  $rbF.Text = "Off"
				  $(Get-Variable "$dir.name" -ValueOnly).Controls.Add($rbF)
				  New-variable -name "stat_$dir.name" -value $(new-object System.Windows.Forms.Textbox -Property @{
					Name = 'SSvar'
					Location = New-Object System.Drawing.Size(110,15)
					Size = New-Object System.Drawing.Size(100,23)
					Text = "Off"
					})
				  $(Get-Variable "$dir.name" -ValueOnly).Controls.Add($(Get-Variable "stat_$dir.name" -ValueOnly))
				  checkSiteStatus $dir.name

		$i += 65

	$cv += 1
	if ($cv -ge 4)
	{ $cv = 0}
