How to Set Default TAB in particular Menu Tab in Menu Bar

I have some queries in this code. This is the menu bar JavaScript in this it has many tab. When I run this code it automatically click in Second TAB instead of First TAB.

JAVASCRIPT CODE.

   var dolphintabs={subcontainers:[], last_accessed_tab:null,

    revealsubmenu:function(curtabref){
    this.hideallsubs()
    if (this.last_accessed_tab!=null)
        this.last_accessed_tab.className=""
    if (curtabref.getAttribute("rel")) //If there's a sub menu defined for this tab     item, show it
    document.getElementById(curtabref.getAttribute("rel")).style.display="block"
    curtabref.className="current"
    this.last_accessed_tab=curtabref
    },

    hideallsubs:function(){
    for (var i=0; i<this.subcontainers.length; i++)
    document.getElementById(this.subcontainers[i]).style.display="none"
    },

    init:function(menuId, selectedIndex){
    var tabItems=document.getElementById(menuId).getElementsByTagName("a")
    for (var i=0; i<tabItems.length; i++){
    if (tabItems[i].getAttribute("rel"))
        this.subcontainers[this.subcontainers.length]=tabItems[i].getAttribute("rel") //store id of     submenu div of tab menu item
    if (i==selectedIndex){ //if this tab item should be selected by default
    tabItems[i].className="current"
    this.revealsubmenu(tabItems[i])
        }
