[Closed] spinner value question

hello all. i have this strange problem with a really simple script.
i simply made a rollout with a spinner and a button to assign the value of the spinner to the height of my parametric object. no big deal
But when i try it its acting really weird. For example; if i say my height is 350 it goes up to 2000, plus my spinner can;t go higher than 100 but the range i assign to it go up to 2000.

I use centimeter for scale so maybe there a “UseWorldUnit” or something like it.
if someone can spot the mistake a mide i would be really grateful.

thanks
here my code

macroscript  sizechanger  category: "mytool"
 (
 global sizeChanger_Rollout
 global sizeChanger_floater
 global sizeval 
 
 
 	rollout sizeChanger_Rollout "size Changer"
 	(
 		spinner sizeVal "value" range:[0,100,2000] type:#integer width:100 align:#center
 		button Do_but "Do" width:100 align:#center
 		on Do_but pressed do
 		(
 			$.height = sizeVal.value
 		)
 	)
 	
 	if sizeChanger_floater != undefined then CloseRolloutFloater sizeChanger_floater
  sizeChanger_floater = newRolloutFloater "sizeChanger v1.00" 130 120
  addRollout sizeChanger_rollout  sizeChanger_floater
