Dynamic Dropdown boxes in each row ?

[Lucour]

Hi,

I have some Javascript code, that allows the linking of 4 different dropdown boxes on an .asp page, each depending on the selection from the previous box. This works great. However, this is a Purchase Order form that I am designing, and I need the ability to make these same selections on 5 different line (items) ? How do I duplicate the code from Line 1, and get it to work on the next 4 lines ?

Thanks !

PS: I can provide my java code if needed.
