I was following instructions to add a plugin – they said to change something in the footer.php

I've really messed it up and all I get in the footer on my blog is:

Parse error: syntax error, unexpected $end in /home/jillc/public_html/wp-content/themes/flexibility2/footer.php on line 87

Then I tried to fix it and made a bigger mess.

Where can I put get the original code in the footer.php to get it back to normal?

Thanks, Jill
