The snag about this is that one ends up with the number of cells = rows 
x columns
rather than just rows.

This is also rather fun:

put the number of groups of group "myGrid"

To compound my folly, I thought a dataGrid was a group of fields:

it ISN'T, it is a group of groups and is very odd indeed.
