Initialize a Date range Prompt

[Ann]

Hi Guys..

Can anybody help me out in knowing how to initialize a date Range prompt.

Let me explain the scenario..

I have a drill through report. I have a date range prompt in the child report assigned to a parameter say ?P1?

Now I am suppose to pass a value to this parameter ?P1?

Note:
1. I am not suppose to make any change to the child report.
2. In the parent report I have three kind of prompts:
    Two date prompts- for start date and End Date(enabled only when my time bucket selected is Daily)
    Two value prompts- For week start date and week end date ( enabled only when my time bucket selected is weekly)
    Two value prompts- for start month and end Month(enabled only when my time bucket selected is Monthly)


Please reply If any solution for this. This is an urgent requirement..
