Vista - Using a variable from within a function

Having trouble with this - would like to re-use the same function to step
through a number of input boxes before writing to a file - however, the
function drops out afer obtaining the variable ($x) and does not allow me to
re-use it - I'm sure there is a simple solution but have been unable to find
it - trying to add the variable $x to the input file:

$date = ( get-date ).ToString('yyyymmddss')
$file = New-Item -type file "$date-freespace.txt"

#-------------------------------------------------------------------------------
function inputbox {
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void]
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

$objForm = New-Object System.Windows.Forms.Form
$objForm.Text = $inputtext
$objForm.Size = New-Object System.Drawing.Size(300,200)
$objForm.StartPosition = "CenterScreen"

$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter")
{$x=$objTextBox.Text;$objForm.Close()}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape")
{$objForm.Close()}})

$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,120)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = "OK"
$OKButton.Add_Click({$x=$objTextBox.Text;$objForm.Close()})
$objForm.Controls.Add($OKButton)

$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Size(150,120)
$CancelButton.Size = New-Object System.Drawing.Size(75,23)
$CancelButton.Text = "Cancel"
$CancelButton.Add_Click({$objForm.Close()})
$objForm.Controls.Add($CancelButton)

$objLabel = New-Object System.Windows.Forms.Label
$objLabel.Location = New-Object System.Drawing.Size(10,20)
$objLabel.Size = New-Object System.Drawing.Size(280,20)
$objLabel.Text = $objectlabeltext
$objForm.Controls.Add($objLabel)

$objTextBox = New-Object System.Windows.Forms.TextBox
$objTextBox.Location = New-Object System.Drawing.Size(10,40)
$objTextBox.Size = New-Object System.Drawing.Size(260,20)
$objForm.Controls.Add($objTextBox)

$objForm.Topmost = $True

$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()

#$x
}
#--------------------------------------------------------------------------
$inputtext = "Enter the external IP address"
$objectlabeltext = "Please enter your info here:"
inputbox
add-content $file $x
get-content $file | out-file 'd:\input.bat'

Hello Jobbsy,

You can set the textbox 'multiline' property to true and resize it so the
user can input multiple lines and then write it to the file.

one you are trying to write to the file.
Try replacing $x with $global:x
