Multiple Scripts
If you have two or more scripts that use the onload event, probably only one will run (the last one).
Here is a solution for starting multiple scripts onload:
   1. Delete or comment out all the onload assignments, onload=initScroll and things like that.
   2. Put the onload assignments in the body tag like in this example, note that they must have braces ().
   Example: <body onload="initScroll(); initTooltips(); initMenu();">
