Slider won't work in class

This is the Error;

Hi.

Change:

sortFisk[1].x+=10;
gulFisk[1].x+=10;

To:

sortFisk[0].x+=10;
gulFisk[0].x+=10;

The two arrays have only one element in each and the index of the first element in an array is 0.

hard coding those array elements is a bad idea, in general. plus, you'll eventually want to account for larger (than 1) array sizes (or there's no proint in using arrays).

so use:

function onTimer (event:TimerEvent): void{

for (var i: int = 0; i < sortFisk.length; i++)
sortFisk[i].x+=10;

// there should be an if statement about what to do when .x > stage.stageWidth
}

for (i = 0; i < gulFisk.length; i++)

gulFisk[i].x+=10;

// there should be an if statement about what to do when .x > stage.stageWidth

}
}

p.s.  these:

var yelFisk: Sprite = new GULFISK;
var blaFisk: Sprite = new SORTFISK;

should be:

var yelFisk: Sprite = new GULFISK();
var blaFisk: Sprite = new SORTFISK();
