Problems with Error "1084: Syntax error:expecting rightbrace before end of program."

I can not figure out what i need to do with this because I keep getting the same error:

"1084: Syntax error:expecting rightbrace before end of program."

Here is my code:

begin.onRelease = function() {

rnd = random(8);

if (rnd>3) {

  if (rnd==7) {

   rnd=11;

  } rnd = rnd-7;

} rotate = true;

}

onEnterFrame = function() {

if (rotate) { 

wheel._rotation += ((rnd*45)-wheel._rotation)/10;

}

Thank You.
