Default ACCESS: Calculation

I am making this Vehicle FORMs in database ACCESS. I have total previous and current reading of Mileage then i used the "text box" control for computing the Actual Mileage... i sum up with this calculation in text box.

Control Source: =Sum(([km reading current]-[km reading previous]))

I get the total mileage but in the next record it appears the same total mileage...

How that it happens? Please help me how to calculate?

Thanks
