Word Range=?

I want to create a table and tries it with this row.
word_document_main.Range.Tables.Add(X, 1, 2)
It wants a specific value instead of "X".
The Value have to be Range as Word.Range
What is that for value?
Can you give me any example of an value?

Word_Document_Main is declared as Word.Document

Thanks...

Nm.
I found it.
Declared a vaiable as
Dim range As Word.Range = word_document_main.Range(0, 0)
And then it worked
