These are the most common linking code problems:

• Incorrect Copy and Paste – Even deleting one character can compromise our ability to track accurately.
• Front Page Character Insertion – The Web page editor adds 'amp;' to every '&' in the LinkShare code. This is because the character '&' is represented in HTML as '&'. To prevent this, paste the code in Notepad first, then copy and paste the code in the HTML view of FrontPage, or do a search and replace and change occurrences of  '&' to ‘&’ in the link URLs.
• Eudora Alteration – Email applications like Eudora will alter the code within the Email. To amend this impediment, log in at http://www.linkshare.com and generate the code directly from your account.
