Type Mismatch Runtime Error

Hi all,

I seem to be getting a type mismatch error or the following line:

Visio.Application.Windows("Document.vsd").Activate

I am running this line in excel, trying to extract data from visio.

I thought that a type mismatch error would mean that the name of the document is wrong. Is this right? Could it mean something else?

Any advice would be appreciated.
