RE: [PHP] global/local var in a function

[Niklas Lamp�n]

This is because it creates a new "thread", atleast I think it so. Use
global variables to prevent this from happening:

i = 0;

function change_check_all(tree_item) {
    a = document.all[tree_item + "_check"];
    b = document.all[tree_item + "_count"];
        // changed the line below
    for(i = $GLOBALS[i];i<b.value;i++) { 
      if (a.value=="off") {
        change_check_to(tree_item + "_" + i, 0);
      } else {
        change_check_to(tree_item + "_" + i, 1);
      }
      change_check_all(tree_item + "_" + i, i);
    }
}
