Error when drawing lines, Please help

Flash doesn’t seem to like this:

drawit = function (b, c) {
    _root.lineStyle(1, #666666);
    _root.moveTo(points**.x, points**.y);
    _root.lineTo(points[c].x, points[c].y);
    _root.moveTo(points**.x, points**.ema);
    _root.lineTo(points[c].x, points[c].ema);
};
**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 11: Operator '=' must be followed by an operand
         _root.lineStyle(1, #666666);

Total ActionScript Errors: 1      Reported Errors: 1

I wasn’t aware that I was using a “=” operator. What does this error mean?
Thank you so much for any help
