I am in process of making an excel file for my costs.
The file contains: Date, Project, costs, discription. All of these are in a
"List" so for example i could look for only a certain project.

My question is:

1. How do i sort by date on the list. My date format is set to
"Day-Month-Year". But when i sort by date it only looks at the first numbers
which is the day, therefore not conidering month or year!

2. Under the costs colum, i have added a total costs (formula =SUM(D5:D15)).
This works fine until i use list to view only one projct. At this point the
cell will show the same value and if i want to get the total of one project i
have to do the formula again. Is there a way so this cell will always show
the SUM of the cell above it?

Thanks in advance
