I need someone who can fix two bugs for me

Hi, I need somebody who can fix two bugs for me on a PHP script. The first bug is basically fixing a "change password" bug. When you click on the link that is sent to your email an error comes up on top of the site that says: /home/content/f/4/3/f43232wsqs/html/includes/functions/[login to view URL] on line 29 The second problem is basically when a user signs up for an account they are able to use the same email address on multiple accounts. My budget for this project is $20. This should be very easy for an experienced coder.
