How to count percentage on report?

[yosiro]

In the report i have some value like these:

Idstudent-------Score
1-----------------------70
2-----------------------80
3-----------------------50
4-----------------------40
5----------------------100

So i want to add an information about the percentage of how many student who have score above 70 at the footer report.

The information above tell us that there are 3 persons who have score above 70 (the result must be (3/5*100%), so how to calculate them in access report?

Use a DCount() to find out how many have over 70 and then divide it by a DCount() of all rows.
