[thelist] advanced JS question - object scope issue perhaps

hi Tom,
I didn't see any reply to this, and I'm not sure if you got it already.. 
but here's a couple of thoughts.

>function DynamicHelp(nDelay, sContainerID, sClassName) 

>	var oContainer = document.getElementById(sContainerID);

you've scoped the oContainer variable to the DynamicHelp function.

>function show(){
>	if(nDelay){	
>		oTimer = setTimeout(function(){oContainer.style.display = "block";}, nDelay);
Show is called as an object method, but when the setTimeout evals the 
anonymous function, oContainer is out of scope. You need to assign 
oContainer as a property of your object, and refer to that object by 
name (not 'this'.. this is also out of scope when the setTimeout evals).

... I think. Does that help, did you arrive at the same place?
