Do you have Word's 'update fields before printing' option checked? That said, I'm surprised the fields don't calculate automatically during the mailmerge. There is no 'openxml component' involved, so I wonder how you're doing this.

You can also update all the fields by Ctrl-A, F9.

Hi,

as is said before, the option is set and if i upate the fields manually, the fields get updated.

Have you opened the file? Do the fields get updated before printing?
