Please start your investigations using the AHAH Example in the Examples Project (http://drupal.org/project/examples) and http://randyfay.com/ahah. If you build a form starting with that foundation, then please come back for help at that point. Thanks, -Randy On Thu, Mar 10, 2011 at 9:10 PM, Austin Einter <austin.einter@gmail.com> wrote:
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
