You are not doing anything wrong Ed. Mine stopped working also.So have a few others in the support threads for the product:

One thing about Blogger - they make frequent changes. What works today may never work again.
Biggest problem with scripts like this that are widely shared is that you can't expect them to last long.
Almost better to share the concept and instructions and suggest some possible automation solutions and then have everyone develop their own tool, script or macro.
I am working on some alternatives with Easy Blogger Creator - it might even work better.
