Edit metadata title to equal filename
I want to create a simple Adobe Bridge metadata template where the only change is to add the existing filename to the metadata title.
i.e. my filename is; Some exciting descriptive title.jpg and I want that image metadata title to be Some exciting descriptive title. This will be used to batch-update a folder of carefully named images so each carries its filename in the metadata title of that image.
I have many hundred images to process once I get this working. Cut-and-past the filename is a non-starter.

I have tried many things, including the above, which, of course, does not work.
Any guidance is gratefully accepted, Regards Paul
