Updating field forms using VBA

Hi,
I have 10 labels on one page in word, I would like to create a macro which will update all of them after filling with text the first field form. It will be changed every week what is the best solution for it?

It looks like that:

Network name: xxx
Username: yyy
Password: (this part must be automatically changed by macro)

I used thew following vba solution but it doesn't work:

Sub CopyField()
Dim Temp as String

Temp = ActiveDocument.FormFields("Text1").Result
ActiveDocument.FormFields("Text2").Result = Temp
End Sub

Thanks in advance.
