Getting error when I run code more than two times

[Clnprof]

I'm trying to scrape several web sites with a code. I could scrape 2 sites but now code doesn't work. It show me "NameError: name 'inf_rest_name' is not defined" when I try to get information about other website. Can you tell me what can I do to evoid that?... what is happening if it was working perfectly with two sites before?
Thank you so much in advance for your suggestions.
