I would try using a slider in this case, which would allow having more AP options without having to create multiple buttons, then trigger server to actually set it as Chris stated.
PHP Code:
new GuiSliderCtrl("AP_Slider") {
profile = GuiBlueSliderProfile;
x = 10;
y = 10;
width = 160;
height = 20;
range = {0,100};
value = 30;
ticks = 10;
}
