Need to declare variables based on textbox input after a button click-CodePudding

I am attempting to create a GUI for a script I wrote a while back. I have had a little trouble with it; I would like to have the "Submit Entries" button log the data entered by the user and assign it to variables($fromcompname, $tocompname, $userid) I am not sure if I need to have a function that pulls the input in the textboxes and assigns them to those variables or what would make this work.

The form itself is in xaml which I made in VS Pro and then I moved it to vs code as I am using powershell to run this script. The Window appears with all the elements I am just not certain how to get the "submit entries" button to log the data input by the user and pass it to the rest of the script to include the "transfer data" button. If there is a question you need to ask me to better understand the intent please do, I am hoping to find an answer. Thank you.

Code below:

As TheMadTechnician commented, you need to set up variables for the TextBoxes in your gui, rather than the Labels.

To do that, you will have to give those text boxes names too like:

<TextBox x:Name="fromcompany" HorizontalAlignment="Left" Margin="290,15,0,0" TextWrapping="Wrap" Text="Old PC" VerticalAlignment="Top" Width="120" FontFamily="Times New Roman" Grid.Column="1" Height="16"/>
<TextBox x:Name="tocompany" HorizontalAlignment="Left" Margin="290,38,0,0" TextWrapping="Wrap" Text="New PC" VerticalAlignment="Top" Width="120" FontFamily="Times New Roman" Grid.Column="1" Height="16"/>
<TextBox x:Name="userid" HorizontalAlignment="Left" Margin="290,61,0,0" TextWrapping="Wrap" Text="User ID" VerticalAlignment="Top" Width="120" FontFamily="Times New Roman" Grid.Column="1" Height="16"/>

and then create variables to be able to reference them

$fromcompanyTB = $window.FindName("fromcompany")
$tocompanyTB   = $window.FindName("tocompany")
$useridTB      = $window.FindName("userid")

Inside the Click() event handlers you need script scoping to be able to use these variables, otherwise they will simply be variables, local to the scriptblock:

$subbttn.Add_Click({
    $script:fromcompname = $script:fromcompanyTB.Text
    $script:tocompname   = $script:tocompanyTB.Text
    $script:userid       = $script:useridlabelTB.Text

    Write-Host "$script:fromcompname  $script:tocompname  $script:userid"
})

The same goes for $transbttn.Add_Click({})

Finally, you need to put a space in front of Content= in the two last <Label lines, otherwise the Xaml is invalid.
