Using variable value as object name... help!

This shouldn’t be too hard for someone with a little more experience…

[AS]
stuff = setInterval(“fun”,20);
myVar = “stuff”;
clearInterval(myVar);
[/AS]

Obviously, the above clearInterval won’t work, because the clearInterval looks for “myVar” instead of “stuff”. I want it to be the other way around.

I tried using the following, but with no luck.
[AS]clearInterval(this[myVar]);
clearInterval(_root[myVar]);[/AS]
