[Closed] Why the script can't Correctly run ?

the theColor is undefined and doesn’t have a “color” property

(
try (destroyDialog change_wirecolor) catch ()

--global change_wirecolor
fn yansegj =
	(
		if selection.count == 1 do
			(
				if (classof $.material == Standardmaterial) or (classof $.material == Vraymtl)
				do (change_wirecolor.theColor.color = $.material.diffuse)
			)
	)

rollout change_wirecolor "Object Color Changer"
	(
		on change_wirecolor open do (registerRedrawViewsCallback yansegj )
		on change_wirecolor close do (unregisterRedrawViewsCallback yansegj )
		colorpicker theColor "Wireframe color:" color:[0,0,255] 
		on theColor changed new_col do $.material.diffuse = new_col
	)
createDialog change_wirecolor --modal:true
)

It is better to declare the rollout as global and access theColor as change_wirecolor.theColor from outside.

Thanks all !!
