Firefox HTML Code

[A.D.S.]

Okay,

So I have a script in Javascript, which basically puts a textbox on a popup.
And then writes some text in it.

e.g.

<textarea cols=80 rows=10 onFocus='this.select()'>
[img]justexthere&centrex=500moretextnow[/img]
</textarea>

However, my problem is that it changes the "&cent" to a HTML code of: ¢. Which I have no idea how to stop this, so can anyone tell me how please
