I have a base form having 20 main fields. and when a user prompt a selection from dropdown control in form1, it should redirect to form2. and user can able to fill all the data and click submit button. then again the form1 with appear where it can able to get the totals from form2. Can any one please enlighten me how can I do it?

instead of usign two forms, you can just use two views. and switch the views.

other wise you will have to write code to achieve this functionality
