Date Query (last Week, Last 2 Weeks, Last Month, Last Year, All)

Hi

Would be great if I could get some help on this:

I have big table that gets updated almost every day with new data. There is a date column. I have a Form where I can enter queries. I need to add a panel where I can spcify if the query should involve the data should involve the date from last week only, from the last 2 weeks, from the last month or if the query should involve the overall data.:confused:

It somhow need to be check what the date is today and then caclulate back.

Any help on this would be much appreciated.:D

Thanks
Daniel
