Powershell: Output an array item to Rich textbox

Alright, some changes had to be made.

You had a space in between Out- and null when adding types at the top of your script which caused an error, so delete the space.

Second change, you can't use the name $czar to reference both the button you click for a czar card, and also the list of possible values for the czar cards, so I renamed the list of cards to $czarValues.

Next, you need to define the cards at the top of the script, rather than at the end, or else you'll have an error the first time the script is loaded which was happening to me, so I moved the card definitions from the end to the top.

Finally, since we changed the name of the card array to $czarValues you also need to change the value of the Add_Click handler as well, so change this:

$handler_Czar_Click= {
$richTextBox1.Text =  $czar | Get-Random | Out-String
}

to this:

$handler_Czar_Click= {
$richTextBox1.Text =  $czarValues | Get-Random | Out-String
}

One more thing, how to populate values in your white cards.

$card_OnClick= {
$richTextBox2,$richTextBox3,$richTextBox4,$richTextBox5,$richTextBox6,$richTextBox7,$richTextBox8,$richTextBox9 | % {$_.Text = $white | Get-Random }
}

With all of these changes, the game now mostly works, as seen here:

The finished code with the changes I made.
