What Is The Best Option?

[Byronwells]

Alright guys

I have spoken to my different coder and they tell me that I should use some sort of java/javascript...

I am using a membership script. I would like to modify the add categories page.. At the moment it only allows me to do create a main category.. I would like to change this to be able to add sub categories..

I have create the extra tables on my db.. But now I need to know how to link them together and what javascript script would you recommend...??

[servlet]

There's no simple answer to you question.. seems that you don't know basics of java web programming or web development in general.

If you are doing this in servlet/jsp you have to learn the technology first
