Hi richmondjim,
1. Expand the size of the Page Header Section to about the size a page.
2. Use the Line Drawing tool (Insert Line) to draw 30+ lines, depending on the total possible number of Detail Lines on your page.
3. Right-click on the Report Header Section and select the Format Section, or Section Expert (depending on your version of CR.
4. Highlight the Report Header and check the "Underlay Following Sections"
As Brian said, this will cause the Header Section to act as a watermark and your detail lines will 'overlay' the lines that you drew in the Header area.
It will take a little finessing to get the lines in place, but this does work.
Regards,
