#Region ### START Koda GUI section ### Form=c:\users\paulo\documents\gui.kxf

Global $Amount = GUICtrlCreateLabel("Amount", 176, 80, 40, 17)
Global $AmountInput = GUICtrlCreateInput("", 224, 80, 57, 21)

GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

$x =

This one is just a test, but I want the value of $x to be whatever numbers the user types in.
