Please help me correct my mistakes!

Please post a question and format your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Sorry already fixed! Help me please!

Please post a link to the challenge.

  1. The radio buttons should have the same value for the name attribute to create a group.
  1. The submit button should have an id of submit on it.
