Plz Help Me Clean Up My Script

I am pretty new to Javascript so this is some ugly code I wrote to do the purpose I desired. You can probably get the drift of the code if you look into it. I am having problems with all the timeouts because sometimes they don't happen in the right order. I was wondering if it would be better to use if/then statements to check the url of the iframes to see if they have loaded before executing next command.

Please, Please Help me with this!

I supposed I should explain all of this more clearly first..
function rr= textbox and button for loading rating info of specified user in Iframe "ratingfrm"
function manlogin= login form for yahoo users which targets a hidden iframe "loginframe". This must do several things in order:
1.Log out of yahoo in "loginframe".
2.Submit login form in "loginframe" Only after step 1 is finished.
3.UNhide "loginframe" after step 2.
4.Change url of Iframe-"ratingfrm" based on value of user on form.

Code:

---

<script type="text/javascript">
function rr(){
var ratename=document.rateform.ratebox.value;
window.ratingfrm.location="http://profiles.games.yahoo.com/games/profile2?name="+ratename+"&intl=us&consolidater=spades.yahoo";}

function manlogin(){
sn=document.manlog.login.value; addy=window.ratingfrm.location="http://profiles.games.yahoo.com/games/profile2?name="+sn+"&intl=us&consolidater=spades.yahoo";
window.loginframe.location="https://login.yahoo.com/config/login?logout=1";
setTimeout('document.manlog.submit()',2000);
setTimeout('hideiframe(ifrm1)',3000);
setTimeout(addy,3000);
}

function hideiframe(element) {
    var style;

    if (typeof element == 'string')
      element = document.getElementById ? document.getElementById(element) : null;
    if (element && (style = element.style))
        style.display = (style.display == 'none') ? '' : 'none';
}


</script>

I'm not going to try rewriting that code so that it works. I will say that time outs are not multi-threaded. This means that while one is waiting, so are the others. In fact, sometimes when one is waiting, others will not even begin to wait. So, instead of having:

Code:

---

setTimeout('document.manlog.submit()',2000);
setTimeout('hideiframe(ifrm1)',3000);
setTimeout(addy,3000);

---

You should probably have:

Code:

---

setTimeout('document.manlog.submit()',2000);

---

Then, at the end (or possibly at the beginning) of document.manlog.submit(), have:

Code:

---

setTimeout('hideiframe(ifrm1);addy()',1000);

---

This of course would require addy be made into a function.

There could be other problems.
