Dynamic form

Hi

My problem is as follows

In a form I have a set of three input fields, respectively, date, quantity and number and two button Add and Delete.
What we have to do is: if I select the Add button, i must to replicate the series of three fields as many times as those indicate in the field quantity.
After that, the field quantity must take the value "1" for all quantity field replicate.
If I click the Delete button should be able to eliminate a quantity at a time.
Then I must retrieve the values of the fields created with javascript in asp.


Can you help me?
I'm not very practical in javascript.

Thanks in advance

 

I can do it, but it's not that simple, so it won't be free... PM me if you are interested
