Cell Calculations

[Adam_TechSupport]

Hi. I am creating an expenses form and need the totals in calls to be
calculated, example below:

[Date1][Mileage 1][Miles 1]
[Date2][Mileage 2][Miles 2]
[Date3][Mileage 3][Miles 3]
[Date4][Mileage 4][Miles 4]
[Date5][Mileage 5][Miles 5]
[Date6][Mileage 6][Miles 6]
[Date7][Mileage 7][Miles 7]
[Total Miles]

I need the form to calculate the total miles from [Miles 1] - [Miles
7] and have the total displayed in Total Miles.

Any help would be appreciated

Thanks

Adam
