You really shouldn’t use a component like “set slider” that expires the object in question in tandem with “get connected” - you can set up a loop where you expire the thing, which expires get connected, which triggers the change, which expires the thing, ad infinitum. See my description here. You also shouldn’t ever expire a “Create Slider” object after the HUI window has launched - it will redraw the entire window. Modifications to an object in the HUI window MUST be made through a “Set” component (from the HUI Output tab). Here’s how I’d approach this:
