hy,
if you have found the answer plz send me a copy...
i'm having the same type of problems...
I want to modify or to create a new select option when someone clicks a button.
1. I extract some values from a database
2. i want when someone clicks a button, in the same page, to load other values from
the database and put them there
it's a sort of dynamic loading ...
thanks for reading and i will help you if could solve this problem..
the part with inserting values from database to the form is done but the rest of the
part is done in a javascript function that does not works...
