I keep getting an error: UnboundLocalError: local variable 'TweetID' referenced before assignment [SOLVED]

Question

I'm having a problem with an error: UnboundLocalError: local variable 'TweetID' referenced before assignment.

Now please, don't crap on the layout and functions of this code. I posted the entire code just in case since I don't know where the mistake is. I'm still new and I know it makes no sense, but 99% works, except this part. I really can't find the reason of the error, I know what it means but I don't see the problem.

A little background: I have to pull a certain tweet from a database and accept or reject it. When Accepted, it tweets to twitter. When rejected, you leave an explanation why. Kind of like a moderator. Moderator ID and StationID (where the tweet was posted) are also sent to the database.

If you need more info I'm happy to supply. Other constructive feedback is also appreciated, but I'm a real newbie so I can't deal with anything too complicated:)

As Sylvester Kruin correctly noticed, you should not mixing variable and function names. Consider snake_case for variable names:

def Accept():
  tweet_id = TweetID()
  cur.execute(f"UPDATE Bericht2 SET acceptrejectposted = 1 WHERE tweet = {tweet_id}")
  cur.execute(f"UPDATE Bericht2 SET moderator2mod_id = {mod_id} WHERE tweet = {tweet_id}")
  print('TWEET ACCEPTED')
  conn.commit()
  PostTweet()
