UI slider - jquery - smoothing out - working with opacity

I am working on my site here: http://www.ryancoughlin.com/ and if you see at the bottom the slider, i am using a part of the UI jQuery docs here for it: http://docs.jquery.com/UI/Slider

I am using it to change the opacity of the content up top (if you click the + sign you will see what I mean, then play with the slider)

Right now it is very rough in changing, if you go to the end or the beginning. As in if you go all the way to the end it goes the light gray, where it should be black.

 I am trying to find a way to smooth it out. Right now in my CSS I have:

#panel_contents {
    background: black;
    filter:alpha(opacity=85);
    -moz-opacity:0.85;
    -khtml-opacity: 0.85;
    opacity: 0.85;
    height: 100%;
    width: 100%;
    position: absolute;
    z-index: -1;
}

That contains the styles for the box that slides down. And I am just adjusting:

    -moz-opacity:0.85;

Should I do all of the others as well? My jQuery is here for the slider:

Any ideas on what I can do?

Thanks,

Ryan

The min and max has defaulted to 0 to 100, because minValue/maxValue have been changed to min/max.
So, at the end of the slider, it becomes .100 (which is why it is white).

It is no longer minValue and maxValue, but min and max.

//line 4-5
//			minValue: .0,
//			maxValue: .98,
min: .0,
max: .98,

Ok, understanding what you tried to do now.  Adding the "." does not work.  1-9 becomes .1 to .9
		$('#slider_callout').hide();
		$('.slider_bar').slider({
			handle: '.slider_handle',
			min: 0,
			max: 100,
			start: function(e,ui){
				$('#slider_callout').fadeIn('fast');
				console.log("started");
			},
			stop: function(e,ui){
				$('#slider_callout').fadeOut('fast');
			},
			slide: function(e,ui){
				$('#panel_contents').css('-moz-opacity', ui.value/100.00).text(ui.value);
				console.log(ui.value);
			}
		});

So changing the minValue to min and adding in the math you put it, fixed it up?

Thank you for your help!
