Hi All I am quite new to AHAH, strugling to find how it works. I referred documentation and poll module. I want 3 fields in a fieldset, *Company, Start-Date, End-Date*.
I have a button "*Add More Company*", if clicked, it should add a new row having *Company, Start-Date, End-Date *dynamically. How many times user clicks, those many rows needs to be added.
To get the above mentioned form, I have put the code as below. However, on button click, new rows are not adding up.
Please help me to find whats the error with code.
Regards, Austin
