In IE, variables created within a function are local variables.  In order 
to create a global variable it must be defined at the root level.  This is 
not the case in Netscape where all variables are global no matter where 
they are created.

I suggest you create a number of dummy global variables in your original 
code and then assign them on-the-fly.
