Drop Down Lists changing depending on other drop downs

[immoralg]

I want to have a drop down system like this one.  But without the radio buttons.

 

I want to have 3 drop downs but have no idea how to go about it.  I assume I will need to activate some sort of Javascript on the onChange event of the option drop downs.

If you want to do this without reloading the page (as in the example you showed) then you'll need to use AJAX. There's an FAQ here:

Copying the code works fine but as soon as I try to link it up to some dummy content I have in a MySQL database it all scews up.
