Vertical line not connecting

[trident]

I have a report that goes like this:

Page Header
Groupheader1
Groupheader2
Groupheader3
Groupheader4
Detail

In Groupheader1 I have several vertical lines which represents the separation of each title
In Detail, the connecting line to complete the box is found. however, when i run the report there is a space between which i think is the space for groupheader2,3,4

how can i connect the lines to complete the box?



Thank you.

perhaps look at using the line method instead - creates a line across sections
