Simple gui with a button? I'm missing something basic!

[Strydr]

I thought I understood this but a simple script isn't working.  What am I missing?  Yes, I'm expecting to feel very stupid, but thanks for the help!  I was working on learning arrays and all of a sudden realized that I seem to have forgotten some basics!

What am I missing?  Why won't the button activate the function "_TestFunc" "OnEvent"?  Thank you!

Opt("GUIOnEventMode", 1)

$GUI = GUICreate("Test GUI", 400, 400, -1, -1, BitOR($WS_MINIMIZEBOX, $WS_CAPTION, $WS_SYSMENU, $WS_EX_CLIENTEDGE))
GUISetOnEvent($GUI_EVENT_CLOSE, "Quit")

Global $testbutton = GUICtrlCreateButton("test", 100, 50)
GUISetOnEvent($testbutton, "_TestFunc")

GUISetState(@SW_SHOW)

While Sleep(100)
WEnd

Func Quit()
    Exit
EndFunc

Func _TestFunc()
    MsgBox(0, "", "testing")
EndFunc

"Am I missing something basic?"  Yes. 

Use, GUICtrlSetOnEvent($testbutton, "_TestFunc"))  Not GUISetOnEvent($testbutton, "_TestFunc")
