Weapon Switch

I'm creating an FPS and the entire point of it is for it to be dynamic - so I can create levels on the fly just by editing a simple XML file. It was all going fine until I got to the weapon part. I needed a way to dynamically pick up weapons, and toggle weapons depending on how many you had.

Here is my code so far. "WEAPON_Update()" is called in the main loop.

Function WEAPON_Update()
	
	t_weapon = 0
	
	For uw.weapon = Each weapon
		
		If uw\inhand = False
			If EntityDistance(camera, uw\entity) < 3
				weaponpick = CameraPick(camera, 800,600)
				If weaponpick = uw\entity
					Color 0,255,0
					Text "Pick Up" + uw\name$
					If MouseHit(2)
						uw\inhand = True
						uw\active = True
						c_weapon = uw\id
					EndIf
				EndIf
			EndIf
		ElseIf uw\inhand = True
			t_weapon = t_weapon + 1
			If c_weapon = uw\id
				uw\active = True
			Else
				uw\active = False
			EndIf
			If KeyHit(15) Then c_weapon = c_weapon + 1
			If c_weapon > t_weapon Then c_weapon = 0
		EndIf
		
		If uw\active = True
			ShowEntity uw\entity
		Else
			HideEntity uw\entity
		EndIf 
	Next	

End Function

This code doesn't work, but otherwise, I have no other way to approach the situation.

Any ideas?

Thanks in advance,
