Stop a Find.Execute loop

Hello,

This is probably easy, but I don't find the answer. Here is my macro (Office 2007). It enumerates my titles, but when reaching the last one, it loops over it again and again. I have tried the different .Wrap possibilities, but they all give the same result. How can I stop my search after having enumerated all my titles?

AG.

Sub macro1()
Dim rgDcm As Range

Set rgDcm = ActiveDocument.Range

With rgDcm.Find
.ClearFormatting
.Style = ActiveDocument.Styles("Titre 1")...
