Since last two days, i am working on filter data view using forms web
part.This works fine using web part connection for one single field.

My requirement:
-----------------
I have a page with forms web part having two text boxes (Start Date &
EndDate) and Search Button

The data view contains all information about the works users have
posted onthis list. It has a field Created.

I want to filter the data view with the dates entered as start date
and enddate in forms web part.

What i am not able to do:
----------------------------
I have set following filter in data view.

Created Greater than or equal to [Input Parameter]
Created Less than or equal to [Input Parameter]

while, establishing web part connection, i am not able to see two
input parameters. (my question:Should i get two different input
parameters in the list and then map each one to Start Date and End
Date Field?)

Please Guide me on:
--------------------
Is this the right way to get this thing working? if not, please
suggest /provide link to the best method available.
