#5 : Bugs I Found : Work around for doc.AppendItemValue command

First in order to understand issues with the "AppendItemValue" command in the NotesDocument Class, you may have to refer to the following post

The work around would be to use the NotesItem class and its "AppendToTextList" command as illustrated below

    Set item = source.Document.GetFirstItem("MultiValuedField")
    Call item.AppendToTextList(rooms)
