Ordering books

In the hope of gaining some knowledge of SharePoint I've ordered some books:

• Microsoft SharePoint 2007 for Dummies (For Dummies (Computers))
  


• Microsoft Office SharePoint Designer 2007 Step by Step Book/CD Package (BPG-step by Step)


• Microsoft Windows Sharepoint Services 3.0 Step By Step Book/CD Package (Step by Step (Microsoft))

Really struggling with this limiting the report to items within the last 14 days, as previously posted it'd be no problem if it was just a regular view on a list (just filter on '[Today] - 14') but because it's a Data Source that won't work.
