Código JQuery no carga

[Razican]

Hola, resulta que tengo este script en JQuery, pero no me funciona, no carga la página. No tengo mucha idea de Javascript, por lo que no encuentro el fallo.

Código:

$(function(){
$.fn.checkRepetition = checkRepetition(pLen,str) {
	var res = "";
	for ( i=0; i<str.length ; i++ ) {
		repeated=true;
		for (j=0;j < pLen && (j+i+pLen) < str.length;j++)
		{
			repeated=repeated && (str.charAt(j+i)==str.charAt(j+i+pLen));
		}
		if (j<pLen) {repeated=false;}
		if (repeated) {
			i+=pLen-1;
			repeated=false;
		}
		else {
			res+=str.charAt(i);
		}
	}
	return res;
}

$.fn.pass_strenght = pass_strenght(password)
{
	var score = 0;

	if (password.length < 8 || !(/\d/.test(password))) { return 0; }

	score += password.length * 4;
	score += ( checkRepetition(1,password).length - password.length ) * 1;
	score += ( checkRepetition(2,password).length - password.length ) * 1;
	score += ( checkRepetition(3,password).length - password.length ) * 1;
	score += ( checkRepetition(4,password).length - password.length ) * 1;

	if (password.match(/(.*[0-9].*[0-9].*[0-9])/)) { score += 5; }
	if (password.match(/(.*[!,@,#,$,%,^,&,*,?,_,~].*[!,@,#,$,%,^,&,*,?,_,~])/)) { score += 5; }
	if (password.match(/([a-z].*[A-Z])|([A-Z].*[a-z])/)) { score += 10; }
	if (password.match(/([a-zA-Z])/) && password.match(/([0-9])/)) { score += 15; }
	if (password.match(/([!,@,#,$,%,^,&,*,?,_,~])/) && password.match(/([0-9])/)) { score += 15; }
	if (password.match(/([!,@,#,$,%,^,&,*,?,_,~])/) && password.match(/([a-zA-Z])/)) { score += 15; }
	if (password.match(/^\w+$/) || password.match(/^\d+$/) ) { score -= 10; }
	if (score > 100) { return 100; }
	if (score < 0) { return 0; }

	return score;
}
