[Javascript] Making One Selection List Dictate Another's Contents

[Trey H]

I have found one solution, but it is a little strange.  My solution involves 
making 2 identical pages exept that one variable is different.  That 
variable contains the other pages location.  I would have used one page, but 
it didn't work for some reason.

First, change the box.html to what you would like it to look like.  Then 
copy the whole source code to the box2.html file.  In the box2.html file 
make sure the sloc variable contains "box.html".

When you change the parent select box on the box.html page it goes to 
box2.html and changes the child select box accordingly.  This sure works 
visa-versa also.  You may need some more help because the values of other 
input fields in forms don't stay the same as what the user made them.  I can 
easily help you with this, but I need to know what your input fields names 
are and I need a rough copy of your page.
