Changing FN separator

I have started a script here that is adding --Notes-- to the footnotes but hitting some snags. 

What graphic do you want to be placed with it? 

It's very basic, it adds a text frame on a new layer and places the text frame over the footnote location. 

But it's putting 2 on the first page and I can't get it to go through the pages and put 1 down per page.

And I've hit an error now that I can't fix. 

Give us some more details and see what can be done.

Have you an example of what you want it to look like?

You can change to a different stroke, no graphic, except those strokes which have got names like Feer, Woof, Rainbow, Lights, etc.).
