How to get the RUN button back (make it function)

I’m working in Komodo for the second time, and running code. After a few successful runs I got a traceback, and now my RUN button is grayed out. I can’t find documentation as to why it would suddenly gray out.

I believe I’ve fixed the error, but I can’t test the code if I can’t run it. Thanks for any help you can provide.

@jps2019, is the run button in your screenshot? I’m not sure what you’re referring to. How are you running the code? and what Komodo are you running? Edit? IDE? What verion?
