12-step volume bar issue

Hi,

As some of you might notice I’m new around here. Unfortunately I’m just about as green when it comes to Action Script.

The thing is, I’m currently working on a small project which I, against all common sense, agreed to do.
Now, the only thing I can’t figure out how to code is a small 12-step volume bar. For each increasing step a white dot should show, so when the volume reaches maximum 12 dots would be shown. Same goes for when the volume is decreased, each step will remove a dot (from right towards left) until the mimimum of 1 step is reached.
To turn the volume up/down two buttons should be used, a “-” and “+”.

I hope you get the idea.

All kinds of help is truly appreciated. I’m not asking for a design or complete code, “just” a hint or walkthrough. Been trying for several hours now.

Thanks in advance :beer2:

Best regards
STAD
