[jQuery] Slider

[jQuery] Slider

I have 3 sliders on one page.
the value combination of slider1 and slider2 dictates the position of
slider3 handle.
but its not smooth... for instance, slider 1 and slider2 have 30
steps, so is pretty smooth to slide, but slider 3 i can only site to
position at values 10, 20, 30.... it doesnt slide like slider1 and
slider2 do....
is there a way to say, as the sliders are sliding, to move slider3
just as smooth ast the other two?
