This is my actionscript, it says that line 8 needs to have a ; but i can’t figure out where to put it, my code is supposed is to play the set frames if my character is facing the oppisite direction.

onClipEvent (enterFrame) {
if (Key.isDown(Key.SPACE)) {
if (_xscale = 100) {
this._x = _root.BlackMageWalk._x+18;
this._y = _root.BlackMageWalk._y+8;
gotoAndPlay(2);
}
else (_xscale = -100){
this._x = _root.BlackMageWalk._x-18;
this._y = _root.BlackMageWalk._y+8;
gotoAndPlay(18);
}
}
if (_root.Lightning, hitTest(_root.Enemy)) {
_root.EnemySound.play();
}
if (Key.isDown(Key.SPACE)) {
_root.i += 1;
duplicateMovieClip(_root.Lightning, “Lightning”+i, i);
}
if (this != _level0.Lightning) {
if (_root.fire == 1) {
this._y -= 5;
this._visible = 1;
}
if (this._y<0) {
this.removeMovieClip();
}
}
}
