Adding a property to a movieclip

1

Hi,

I have the 4 countries of the UK that get scaled up on click. I because each country is a different sizes geographically they do not scale up by the same amount. I would like to set a pixel scale size like this (scotland is the name of the movieclip)

scotland.expandWidth = 246;
scotland.expandHeight = 406;

The problem I am having is getting this value when the country is clicked, tried few things but nothing works.

trace(MovieClip(evt.target).expandWidth)
trace(evt.target.name.expandWidth);

Thanks,

RK
