Its quite simple, When the slider is touch up, The label will register its thumb position. The issue: When i touch up the slider it is not registering any movement.
Dear @Fryan,
first of all please let me comment that clearer are questions, better focused will be the answers.
Having said that, please find annexed an .aia in which I've used the SliderTools extension (from @WatermelonIce) and in which I've used both the events TouchUp and TouchDown. In both cases the new thumb position is shown, provided that in the Changed event the new thumb position is assigned to a global variable, used by the two other events.
Please also note that the "component" name (shown into Label1), is pretty weird, so I think we can forget it. sliders.aia (13.7 KB)
Last note: in the same .aia you'll find also some other experiments that I did with the standard sliders blocks. I left them in, for your perusal.
