Can't display groupbox in my Powershell GUI

Question

I don't understand why my GroupBox isn't displayed. I would like to display groupbox with several labels but it doesn't work. I've tried to replace the radiobuttons by labels with the code here => https://sysadminemporium.wordpress.com/2012/12/07/powershell-gui-for-your-scripts-episode-3/ I'm a beginner in GUI and I have seen other examples but I can't use this code as I would like. Here is my code :

Can you help me ? Thank you in advance.

Change 2 lines:

$groupBox1.Location = '150,300'

y location is 300, which is off the bottom of your form as it's only 300px high.

$form1.Controls.Add($groupBox1)

Move this line to after you have created the groupbox. So anywhere after $groupBox1 = New-Object System.Windows.Forms.GroupBox

For example:

$groupBox1 = New-Object System.Windows.Forms.GroupBox
$groupBox1.Location = '10,10' 
$groupBox1.size = '400,150'
$groupBox1.text = "Title groupBox1"
$groupBox1.Visible = $true
$form1.Controls.Add($groupBox1)           # line moved here.
