How can you name a slide and then refer to it by name in a hyperlink?

[fkneg1]

Hi,
I want to set up a hyperlink to another slide in the same presentation. The problem is that the slide I want to refer to is in a different position each time a new presentation is set up. I think I have named the slide using the following:

.Slides.Add(rs.AbsolutePosition + 1, ppLayoutBlank)
.Name = "StartSlide"

But when I try and refer to the slide by its name in the hyperlink (as below) the link is not created so it doesn't work.

With .ActionSettings(ppMouseClick)
    .Hyperlink.SubAddress = "StartSlide"
End With

Is there another way that this should be done?
Thanks in advance.
