Question on Volume Control Slider Tut

Used the Kirupa tutorial “Creating a Volume Control Slider.” It worked greatin Flash MX, but for some reason I can’t get the volume to default (or start) set to 100 rather than 0.

I thought that setting the first line to:
[COLOR=royalblue]this.ratio = 100;[/COLOR]
would do it, but it didn’t help. Though the Dragger is all the way up (right) on the slider when it loads, the volume control does not kick in until the the dragger is moved… Am I missing something??

Thanks
