[Closed] Spinner getting the object value

Hi,

I’m testing a simple spinner to set the height of a box.
How do I make the box height value appear in the spinner?
For example, I have a box with a height of 125cm and when executing the script, I want the value that appears in the spinner box to be the value of 125cm and not “0”.

try (destroydialog spinnertest) catch()
rollout spinnertest "Spinner Test" width:130
(
	spinner altura "H:" 
			range:[0,10000,0] 
			width:60 
			type:#integer 
			align:#center
			tooltip: "output height"

		on altura changed val do try 
			(
				$.height = altura.value
			) catch()
)
createdialog spinnertest
