Anyone know how I can embed javascript in a Wiki page without it simply spitting back out my code?

I m experiencing problems with JavaScript and myspace and I m not sure how to fix it. When I m at my myspace "home"- and when I try to do the simple things like update my "friend status" or browse my friends list (either by clicking a page number in my list- or "next")- absolutely nothing happens. I assume that it has to do with Javascript because when I mouse over one of those particular links- it has "javascript:___(___)" on it. I tried updating to the latest JRE- downloading the latest Adobe Flash player- tinkering with the settings- and even cleaning out cache and cookies- yet NOTHING worked...

Just so you know- I m not adding javascript in my myspace profile (I know myspace doesn t allow that). I m just simply trying to do things in my "Home" page like update my friend status- or get past page 1 in my friends list. I just want to get the links that say "javascript:___(___)" to work. Can somebody please help? I really need this to work!

*This issue may not be limited to myspace.

in YouTube- it says- "Hello- you either have JavaScript turned off or an old version of Adobe s Flash Player. Get the latest Flash player."

I just got Java & Adobe s flash player updated- however the sign s still on. May I know what s wrong with it- please?
in YouTube- some clips can be watched whereas some can t; it says- "we re sorry- this video is no longer available"

also- i m using the new video player instead of the default 1. is there any chance i can switch it back?

i think i have a virus on my internet explorer. whenever i click onto a website it bring me to another website. so i click backand go back into it and it usually takes 2 or 3 tries before i get into the website and also on some things i click on they dont work and it says javascript error at the bottom.

what can i do to get rid of these problems?

For one of my assignments at college i am required to validate a phone number- which i have done in JavaScript in conjunction with a button. The code looks like this:
function isNumeric(elem- helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
window.location = "index.html";
}else{
alert(helperMsg);
elem.focus();
return false;
}
}

I am also trying to get the button to take the user back to the index page. Is this possible?

It keeps telling me "Hello- you either have Javascript turned off or an old version of Adobe player." The weird thing is I do have Javascript turned on and I have the latest Adobe player that is why the video loads eventually but the message shows for about two seconds. It s annoying. Does anyone know why?
