				If MouseX() > x Then
					x = x + speed
					frame = Rand(0,5)
				EndIf			
				If MouseX() < x Then
					x = x - speed
					frame = Rand(0,5)
				EndIf
				If MouseY() > y Then
					y = y + speed
					frame = Rand(0,5)
				EndIf
				If MouseY() < y Then
					y = y - speed
					frame = Rand(0,5)
				EndIf
		Case 1
				If JoyX() >  0.5 Then
					x = x + speed
					frame = Rand(0,5)
				EndIf			
				If JoyX() < -0.5 Then
					x = x - speed
					frame = Rand(0,5)
				EndIf
				If JoyY() >  0.5 Then
					y = y + speed
					frame = Rand(0,5)
				EndIf
				If JoyY() < -0.5 Then
					y = y - speed
					frame = Rand(0,5)
				EndIf

		Case 2

					frame = Rand(0,5)
				EndIf
				
				If KeyDown(208)
					y = y + speed
					frame = Rand(0,5)
				EndIf
				
				If KeyDown(205)
					x = x + speed

You haven't declared the variable speed as global.

global Speed = 1

This works.

ohhh thanks.( that was dumb)

ps is there a way to declare all variables as global?

have to do it one by one, but you can do:

Global bob, sue, suesie, fred, jill

instead of

Global bob
Global sue
Global suesie
Global fred
Global jill
