Two Submit from normal form and Modal Form - php

Question

I have a form to enter some details,in that one select control is there,to select some option(Audit ID) .IF the user could not find the correct option,then he can add in using another button in the same form beside of that select control.By clicking that button one modal-form will appear and the input control is there,entering data and saving it,will save that value in one table (table : auditnumber). And the main form will save all entered data in another table(auditplan).So i have two submit buttons saving different value to different tables and the modal form is just optional..in case user didnt find exact option.
Just i tried these code below..but didnt work. the modal form submit button didnt work.
And i dont know whether this one is good idea. Just im beginner in web app.
