😟 There are some issues with your submission. Please check the test report for details.

I'm really confused by the error message.
Is there a plain English explanation of why the way we have used the 'director' macro is wrong, and how we might fix it (it passed thought the validation at http://validator.citationstyles.org/):

1. arts-university-bournemouth: may not have any unused macros
   Failure/Error: expect(available_macros - used_macros).to eq([])

PS, sorry, i don't know how to 'make commits to the current pull request branch' (i don't really now what it means), hence the creating new pull request. Are there instructions on this?

For the repository, we don't allow styles to contain any macros that aren't used. Your current version has one of those, named "director". Deleting this "director" macro will clear the error.

Click the pencil icon at https://github.com/citation-style-language/styles/pull/2903/files (it's on the right, at the top of the style file panel) to start editing.

@Dbelk, email attachments don't work on GitHub, but you can attach them via the GitHub website. See https://help.github.com/articles/file-attachments-on-issues-and-pull-requests/

And you define the "director" macro on lines 23-28, but then don't actually use that macro anywhere in the style. (you are substituting the "director" variable in the "author" and "author-short" macros, but that doesn't involve the "director" macro)

Your submissions also lack correct indenting. How exactly are you copying and pasting the style code into the GitHub window?

You can quickly get the correct formatting by copying and pasting your style code into our formatter at http://formatter.citationstyles.org/, and then update the pull request with the reformatted style (assuming you have figured out how to do that last bit).

Okay, i have now removed the Director macro. Sorry, i thought i needed this in order to use the substitute.
I have also put the text file i was using through your formatter. Hopefully this will meet all your needs.

😃 Your submission passed all our automated tests.

Thanks! And happy to see you figured out how to edit the existing pull request :).

I made a few minor changes, so please start from the latest repository version if you would like to submit more changes in the future.
