Battle events not working

[Bluez]

Hey, i was wondering if i could get some help. On rpg maker 2k3 whenever i try to add a battle event... nothing happens even when i set it to a switch. everything else seems to function fine... anyone know what could be wrong?

I'd  really apreciate if some one gave me some advice...
