Please Help With Error 1086

Hello. I was writing a program. Below is the program I've written. There was an error that said

Scene 1, Layer 'Car', Frame 1, Line 7   1086: Syntax error: expecting semicolon before leftbrace.

I've put a semicolon there and I got about 37 errors about properties and such.

So can someone tell me what is wrong with this program please?

onClipEvent(load)

{

    speed =0 ;

}

onClipEvent (enterFrame) {

if (Key.isDown(Key.UP)) {

    speed +=1;

}

if (Key.isDown(Key.DOWN)) {

    speed -=1;

}

if (Math.abs(speed)>20) {

    speed *= .7;

}

if (Key.isDown(Key.LEFT)) {

    _rotation -= 15;

}

if (Key.isDown(Key.RIGHT)) {

    _rotation += 15;

}

    speed *= .98;

x = Math.sin(_rotation*(Math.PI/180))*speed;

y = Math.cos(_rotation*(Math.PI/180))*speed*-1;

if (!_root.land.hitTest(_x+x, _y+y, true)) {

    _x += x;

    _y += y;

} else {

    speed *= -.6;

}

}
