Re: TempInit -- Expecting semicolon before disabled

no, that's not correct.  you would use something like:

var sample_warning:sampleWarning=new sampleWarning();

addChild(sample_warning);

sample_warning.x = etc;

creating an empty movieclip:

var subGraph:MovieClip=new MovieClip();

addChild(subGraph);

subGraph.graphics.lineStyle(1,etc);
