Stop Func problem

[Command3r]

hello, now i have a script and need it to stop it's function when "F3" is pressed.

but i don't know what's wrong

check that:

HotKeySet("{F2}", "MSG")
HotKeySet("{F3}", "xt")

Func MSG()
$chk = 1
while 1
MsgBox(0, "TEST", "1")
MsgBox(0, "TEST", "2")
MsgBox(0, "TEST", "3")
MsgBox(0, "TEST", "4")
MsgBox(0, "TEST", "5")
$chk = 0
wend
EndFunc ;==>MSG

Func xt()
$chk = 0
EndFunc ;==>xt

While 1
Sleep(200)
WEnd

EDIT: I want it stop wherever which msgbox running whether msg1 or msg2 etc..
