Depends on your report design, but you should be able to solve this a couple of ways. Perhaps the easiest might be to look at running totals set to add the Dutch->answered field.  Another way might be if you have two groups you could create summary fields for each group in the group footer ( suppress it if you do not want to see them) then create a formula that would add the two summary fields and place it where you want it to appear in your report. Finally, if you use subreports then you will need to create shared variables to hold the sums and use in formulas as appropriate.

Hope this give you some ideas and is useful.

Now that I came to think of it, I tried option 2 allready but I can't summaryse the two group sums because I dont know hot to reference them.
