custom quiz module ---adding fields dynamically

Hi all,

I am trying to create a custom quiz module.....since the available quiz module is not upto my needs.... i am not expanding the existing quiz module,,,i am trying to create new fresh module.....

i have coded to create a content type called quiz....appart from existing fields of node.....i am trying to add more fields....

let say

I have added question field and relative two anwser field under question field....

i have created a submit handler naming add more questions...its works fine....

my question is i need to place another submit function which adds answer fields to the respective questions.....

so it looks like

question 1->text field
answer1->text field
answer2->text field

add more answer

question 2->text field
answer1->text field
answer2->text field

add more answer

add more questions

so how to create a submit handler for add more anwser so that it will update only the respective question

i dont want use javascript to do this.....it should be normal.....

you can find an example wat i am trying to do......i am just trying to replicate the same
