[development] Form textfield data retreive

15 Mar 2011

      Hi All
I have a small working custom module. Code is as below.

It's a simple form.

In one line I have 4 fields (company, start date, end date, checkbox).
Below I have "add/remove more companies" button.

If user clicks "add/remove more companies" button, it adds one more line
having company, start date, end date, checkbox fields.

But in the process, it is loosing user entered data in previous line like
company name, start date etc.

Now the question is what logic / tricks I need to follow so that, I can keep
user entered data in newly rendered form.

Best Regards
Austin.
