Hi I found a bit of a bug in ver 1.2 your code has the f1 and f3 keys on the gui set backwards so here is code to fix it
Just need to change the lines with $Radio4 and $Radio6 to what is below
$Radio4 = GUICtrlCreateRadio("F1", 56, 158, 33, 17)
$Radio5 = GUICtrlCreateRadio("F2", 96, 158, 33, 17)
GUICtrlSetState(-1, $GUI_CHECKED)
$Radio6 = GUICtrlCreateRadio("F3", 136, 158, 33, 17)
In your code you had the spot for them backwards is all ie you had
$Radio4 = GUICtrlCreateRadio("F1", 136, 158, 33, 17)
$Radio6 = GUICtrlCreateRadio("F3", 56, 158, 33, 17)
so that if anyone chose f1 for hp pots and f3 for mp pots it was trying to use f1 for mp as well the way you had it. Hope this helps someone as it has me :)
