Code will not run


Hi, one of the files within my work space will not run for whatever reason and there isn’t any errors in the code. I have tried copying the code into a completely new file to see if this would work but unfortunately, it still won’t run. I’ve gathered from this that it must be a problem within the code however this file ran fine the other day and now doesn’t want to work even though i haven’t actually changed the file which is rather confusing.
Has anyone else had a similar problem to me? If so, how did you rectify this? Thank you.

Update: There was in fact an error in the code which was causing the system to not function properly but which has since been deleted and my code is now running fine.
