Why needs my hotkey to be held? It needs to toggle on and off

I have made a triggerbot. The only problem is I don't know why my hotkey isn't working. I constantly need to hold VK_NUMPAD1 to shoot when someone is in my crosshair but I want it to toggle on and off when an enemy is in the crosshair it needs to shoot automatically without holding the number 1 button is my hotkey wrong? Also my game crashes after a new match is starting. I hope you guys have some suggestions. On my previous thread no one replied. Hope someone is out there who can help me. Thanks !
