In a sub-report you can have multiple columns but you must use across then
down layout and not down then across. If that does not solve your problem
then you are going to need some complex coding to identify which records go in
column 1, 2, and 3. You would still need to used the across then down setup.

To set up multiple columns, you use page setup. Found under the File menu in
versions of Access prior to Access 2007.

Hope this helps solve your problem.

I have a members database with people divided into groups or categories etc.
The report I am trying to do is have many columns at the group header level
with only one field - the fullname of all those members in the detail
section for that group. What I would like to have is this information
is snaked through about 3 columns in this detail section. Is there any
way of doing it? Could it be a macro? Except I cannot think how to go
about it!
