Sure Rick,

It's the same old story. I want to create a certain amount of
rectangles based on the amount of records in a table (which can vary)
and update the subform for any new or deleted records (also some other
info if the record has been changed, but not deleted).
But, unlike what everybody thinks, which is some kind of continuous
form of controls based on the records, I want to create a kind of
"Matrix", a nxn grid of rectangles.

So, the user has an interface, say the Main form, to
browse/update/delete the records (in a subform datasheet) and then
click a button that will generate the grid.
The grid will be on a form and shown in a subform control after
created.

Now, once the grid is generated, each rectangle should have the click
event code to respond to the user, who will click each rectangle as
needed and change the color of the rectangle clicked. There are
multiple colors which each mean something different.

When the user clicks a rectangle, a cooresponding record in the table
is updated.
If the user deletes or adds a record, a row of rectangles is added or
removed.

Mathematically (if I have this right) it is a "Cartesian Cross Product"
of the records in
a table with itself. Kind of like how a multiplication or addition
table looks.
The record id is at top and across, labeling each column in the grid,
and at the left
and down, labeling each row in the grid. The user marks the color of
each grid based
on the condition or meaning of combination of a row and column id
value.
Naturally, like squares in a multiplication table, the diagonal
rectangles would represent the pair (id,id).

So given a table with n records, create an nxn grid, labeling the top
and left with the record id, and allowing the user to click a rectangle
to change its color, update the table with the color value chosen after
the click event.

Now, one could, theoretically, upon creating the grid, calculate the
cross product pairs and populate another table, and with that other
table somehow generate each rectangle, of course with the same click
event features as above.

Hope this helps and thanks for responding,

Christopher
