What is the layout of the table?  Is there possibly an AutoNumber primary key?  If so, I might be able to come up with something.

I have a continuous sub form where users enter vehicle costs (mileage, parts etc). They would like the form to display the daily running total next to the last entry for each day, but only for the last item of the day, eg

Date PartDesc Cost Daily Total

29-Jun  Labour £10

29-Jun  Mileage  £20

29-Jun Part 1  £5 £35

30-Jun  Labour £12

30-Jun Part 2 £4.99 £16.99

1-Jul Mileage £20 £20

2-Jul Part 1 £5

2-Jul Part 3 £55 £60

I've created a dsum function & a function with conditional formatting which works, but is too slow to use.

A query seems a better way to go, but the ones I've done have not been update-able so the user can't use it to enter costs.

Any suggestions?

Many thanks
