_WordMacroRun with argument problem

[which1]

Hi everybody,

Sub Bookmarks() is a VBA macro which puts... bookmarks in a Word document. Working fine from autoit with :

_WordMacroRun($oWordApp, "Bookmarks")

Sub Bookmarks(ByVal nbre As Integer) is quite the same macro : I just added a MsgBox for testing purpose. Still working fine from VBA, but no more from autoit with :

_WordMacroRun($oWordApp, "Bookmarks", 2)

I tried (rather blindly) ByVal --> ByRef and ("test", String) in place of (2, Integer) without succes.

I'm afraid I need some help ! Thanks in advance.
