I am looking for the best way to accomplish the following Continuous
Forms concept.

Given:  There are Five Groups A, B, C, D, E

Each group has eight members:  a, b, c, d, e, f, g, h

Each member is seen as a row in a continuous form like:

A a
A b
A c
.
.
.
A h
B a
B b
.
.
.

Each row (member) has a selection checkbox and a lable

The behavior that I am looking for is -- when you click on a checkbox
for any group, the count for that group is reflected in it's lable.

Using Group D as an example, if you check member D b (and it is the
only member of that group selected) then D b's lable shows "1"  -- if
you then select member D g the label updates to "2" and so on until
your reach "4".   If you de-select member D b it's label value
disappears and the value for Group D is refreshed with the total
number of checks for Group D.

When you exceed "4" the number briefly turns into a message like "All
4 Selected" and then back to a "4".

I was thinking of a function using dlookup that accomplishes this, but
I don't want to reinvent the wheel if there is a better method of
letting the user he's exceeded the count for each group.

Thanks for any suggestions,
