>tamar hello, sorry but I need your help I am doing what you told me, but I presents the error in this part

It would be easier to help if you'd pasted in your code and the error rather than attaching a picture, so I have to try to remember what it showed.

I think you need to apply Range to the bookmark:

oRange = oDoc.Bookmarks("whatever").Range()

I'm not 100% sure and don't have time to test right now.
