>>So I thought (I have no documentation) I could pass the parameters in the same order and it might work. (I'm stabbing in the dark here)

If you have the vbaword help file, you can look up the methods in question and see the actual order of parameters. The problem with trying to translate named parameters to ordered parameters is that there could be some named parameters missing, throwing your order off.

from within Word, press Alt+F11 to open the VBA word editor, and then press F2 to open the VBA Word object browser. Type in the name of the function you are working with, and in the resulting list, rightclick it and select help to get the reference for that method.
