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
