function getParam(paramName) {

paramValue = “”, isFound = !1;

if (this.location.search.indexOf(“?”) == 0 && this.location.search.indexOf(“=”) > 1) {

arrSource = unescape(this.location.search).substring(1, this.location.search.length).split(“&”), i = 0;

while (i < arrSource.length && !isFound) arrSource[i].indexOf(“=”) > 0 && arrSource[i].split(“=”)[0].toLowerCase() == paramName.toLowerCase() && (paramValue = arrSource[i].split(“=”)[1], isFound = !0), i++

}

return paramValue == “” && (paramValue = null), paramValue
