Can't figure out what's wrong here (variables)

Hello.
I have a generic class with different methods for movements along x and y coordinates.
Then i have a specific class that extend the base one:this class choose movements based on a variable.
Once i assign a movement it seems i can't change the variable so it can start another movement once the old one is finished (i think the problem is here..how can i tell when it's actually finished?)
These are the 3 generic methods for movement:

Method MoveTowards:int(_x,_y,_steps)
		posx= posx + ( _x - posx ) / _steps
		posy= posy + ( _y - posy ) / _steps
			'it does a check between 2 positions and return true if they are different
	End Method
	'----------
	Method godown()
		speed=5
		posy=posy+speed
	End
	'----------
	Method leftright()
		posx=posx+speed				'start the movement
		If posx >= startx+range			'check against right border
			posx = startx+range		'stop movement
			speed *= -1						'invert the movement by inverting the speed
		Endif
		If posx < = startx-range			'check agaist left border
			posx = startx-range			'stop movement
			speed *= -1						'invert the speed
		Endif
	End
End

Here is the update that should swap between movements:

Method update()
		Local t=100
		Local t2=100
		If posy >= Dbound+20 Then nemico.Remove(Self)			
		If life <= 5 Then movement=2
		If life <= 0
			nemico.Remove(Self)
			ExplosionInit(posx,posy)		
		Endif
		Select movement			'here we decide which movement to assign to the object
			Case 1
				leftright()
			Case 2
				godown()
			Case 3
				MoveTowards(t,t2,10)
				If posx=t Then movement=2		'this doesn't work
		End
	End

I suspect the error is in the last method...but i can't figure out how to tell the method to change movement...

Without complete code it's a guessing game. Have you checked if posx ever equals t? t is defaulting to an Int. Is posx a Float by any chance?

I found it out...i forgot to set all the variables float!

Basically i was comparing and int to a float.silly me.
I guess its time to start programming using strict!

Thanks for pointing me to it (sorry for spamming the reply! just realised i haven't said thank you).

I actually learnt something decent out of it (apart from coding in strict!): i can return a value when the condition inside the method is true so i can play with different status changes (if it make any sense).
