crystal report grand total doesn't show in report footer

I'm working on a report. The sections look like the following:

Report Header
Page Header
- PH1
- PH2
Group Header1
Group Header2
Details
Group Footer2
Group Footer1
Page Footer
Report Footer

I have a couple of questions here:

On the first page, there are two complete group1(group-a, group-b), and part of the data from next group (group c). The vertical lines stop at the end of group-b. Group-a and group-b have grid but group-c has no grid at all. But all vertical lines look fine on the following pages.
I created a few summary objects under report footer, but nothing shows up, not even the text object I put there for testing. I've played around with the section export, but so far, no luck.

Please help me with the questions, thanks a lot. :)

Solution

As for line issue, one solution is to create separate line segments for each section. They need to be carefully positioned to line up vertically and sized to span the exact height. Use the editor dialog because mouse positioning just won't work right.

In old versions of Crystal there must have been a lot bugs because I could crash the app dozens of time before getting it right. Eventually I figured out how to avoid the crashes pretty well but I can't remember the details now. It's a big hassle all the way around.

Diagnosing the other issue is probably easier with a view of the designer.
