Why am I receiving a name error for a name not defined that I haven't included in my code?

Question

Using this code in my website update tool, I receive a NameError: name 'new_link1' is not defined. However I use the name new_link in my code, not new_link1. I am using Jupyter notebooks with some other notebooks running similar code if that might be having an effect. My code is below.

    import requests
    from bs4 import BeautifulSoup
    import schedule
    import time

    # Electricity Northwest Code   
    def get_link():
       url = 'https://www.enwl.co.uk/about-us/financial-investor-relations/information-for-investors/'
       reqs = requests.get(url)
       soup = BeautifulSoup(reqs.text, 'html.parser')

    changing_link = soup.find('a', {'class': 'c-downloads__link js-downloads__link'}).get('href')
    return changing_link

   def handle_changes_to_link(value):
       new_link = get_link()
       if not new_link == value:
            print('New Update from ENWL, remember to copy and paste new link: ', new_link)

   #When an update has occured copy and paste new link into value = 'https://new link here'  below

   schedule.every(30).seconds.do(handle_changes_to_link, value = 'https://www.enwl.co.uk/globalassets/investor-relations/documents/non-password-protected/enw-finance-plc-prospectus-july-2020')
   while True:
       schedule.run_pending()
       time.sleep(10)

And the error I see is:

    NameError: name 'new_link1' is not defined
