I'm having trouble! My code is:

var compare = function (choice1, choice2)

{

if (choice1 === choice2) {

return "The result is a tie!";

}

else if (choice1 === "rock") {

if (choice2 === "scissors") {

return "rock wins";

}

else

{

return "paper wins";

}

}

else if (choice1 === "paper") {

if (choice2 === "rock") {

return "paper wins";

}

else {

return "scissors wins";

}

}

and it comes up as SyntaxError: Unexpected end of input.

Any help would be appreciated!
