  <p>I have tried removing the size argument but it caused more errors in the code. We also tried changing the size tag to something else to see if that helps and it didn't work either. So I'm stuff for what I need to do to make this code work. I am working on it for a class project in school. English is not my first language so I have had a classmate write this up.</p>
  
  <p>Thank you.</p>
