If this is just a data dump then the easiest way is to use the sub total
function.

Highlight the data including the headers, select Data Subtotals

At each change in : prodhiernr
Use function: Sum
Add subtotal to: [check the cost box]

Click OK

If you want a formula to run in a column next to your data then post up and
we'll try to resolve it.

Hi there,

so i have for example :

prodhiernr artnr cost
1110050 123456 50
1110050 123544 60
1110050 234343 70
1110051 534222 90
1110051 353533 100
1110051 124643 80

When de prodhiernr changes to 1110051 i want to sum the total cost for
prodhiernr 1110050 and later on for the other products also (the list
is very long).. Does anyone have a clue how to do this?

Thanks in advance
