Hi Dave,
Welcome to this Microsoft Project newsgroup
Help says: "You can use Microsoft Office Project 2003 groups to categorize
and report project information in a variety of ways. Grouping also allows
you to view summary information of tasks or assignments in sheet views.
In resource views, grouping can provide summary information that is
unavailable otherwise. In task views, you can group by outline codes in a
hierarchical order based on a single coding field. In Task Usage or Resource
Usage views, you can group assignments and timephased information. In the
Network Diagram view, you can apply grouping as you would in any other task
view.
Project provides predefined task and resource groups. If none of the
predefined groups meet your needs, you can create a custom group, make it
available from the menu, and display it automatically in a particular view."
Thus, groups and grouping is an aid to viewing and representing the data and
is not assignable.
However, if you mean a group of people like "painters", you can assign
painters as you can individual resources, though you need to designate
maximum units as, say, 500% for your 5 painters. However, the penalty is
that you cannot then assign an individual resource from within those
painters as Project will treat that as another separate resource.

Hope this helps - please let us know how you get on
