How could i give option to user to choose data for dynamic number of days,such as if user choose the data for 35 days or42 days etc.The data for that number of days should be displayed.Thanks

hi barrysaab,
will you please post your requirement clearly,
with out start date and end date how could the database retrive data if you simply give 30 days or 40 days as your input.
there should be an interval prompt that too the user should give the start date and end date.

Here's one way -

Create a Text Box prompt and name the parameter pDate.
While creation, check out the box that says 'Create Parameterised filter'.
Make sure to allow only numeric values in the prompt (it's a property of the Prompt).
Add a filter to the query and use this kind of expression:

[Date] >= _add_days(current_date,0 - ?pDate?) and
[Date] <= _add_days(current_date,0)
