Table of Contents in PowerPoint VBA

[RayKay]

Hi John, and readers, I'm hoping you can help me on the code below.

It creates a slide with a table of contents. You select slides first then click choose the macro (hyperlinked or not).

I get an error message "Compile error: Sub or Function not defined" at the text I put in red font (half way down).

So grateful for any help, and thank you for your time.
