Nested functions and variables

Hi,



It took me some hours to figure out why my script did all kinds of stupid things - but it came down to this:



function Test1()

{

  var counter=mylist1.Items.Count;

  for(r=1;r<=counter;r++)

  {

     var findme="Test"+r;

     Test2(findme);

  }

}



function Test2(mytext)

{

  var counter=mylist2.Items.Count;

  for(r=1;r<=counter;r++)

  {

      // do stuff

  }

}



Basically, what I found is that changes to the loop variable "r" in Test2 also affect "r" in Test1.

This behaviour is not quite what I expected - even from a simple scripting language ...



How do I prevent that from happening other than constantly keeping track of  potentially nested loops?

All I found in the tutorials is how to make variables globally accessible but not how to restrict them to a "private" level.
