这是一段动画其中一针的AS，意义不用看懂，关键请大家看看有纯语法错误吗？

x=getproperty(ball,_x);
y=getproperty(ball,_y);
if (Number(x)>=390){
    movex=-(movex);}
else if (Number(x<=10{
movex=-(-movex);
    }
if (Number(y)>=290){
    movey=-(movey);
}
eles if (Number(y)<=10{
movey=-(movey);
}

总提示：Scene=Scene 1, Layer=Layer 2, Frame=2: Line 5: ')' or ',' expected
else if (Number(x<=10{

Scene=Scene 1, Layer=Layer 2, Frame=2: Line 6: ')' expected
movex=-(-movex);

Scene=Scene 1, Layer=Layer 2, Frame=2: Line 7: Unexpected '}' encountered
    }

ok!谢谢！我眼神不好 ：）
