i have a table, 5 fields (columns) for manager name, project name, etc,
and another 144 columns giving money spent for each month
so column headers would be:-
manager name, project name, project code, category, identifier
then months going from jan-05 upwards for 12 years, so table has 149
columns and as many rows as records.

what i need is a method where a user can easily update this table
without having to find the correct row / column themselves.

how can i get a value from a user entry cell into the correct cell in
the table.
