URL link in Email Script Token click event is not tracking

Hi,

We have a situation where href  references(URLs) in <a> tag generated via email script tokens are not trackable. Dynamic content which will be sent by an email with links to the user. These URLs are dynamic based on the user preferences. 

• Created an email template with HTML  and CSS text
• Defined an email script token to get HTML text which includes URL links to dynamic content from a custom object  example HTML derived via email script token: <tr><td class="cssclass">Document heading <br /><hr class="cssclass"><a class="cssclass" href="documentlink.com/Display?ab=asdf">DocmentLink Text</a><br /><a class="cssclass" href="documentlink.com/Display?ab=abcd">DocumentlLink</a><br /></td></tr><tr><td class="cssclass">Document Heading <br /><hr class="cssclass"><a class="cssclass" href="documentlink.com/Display?ab=abcd">DocumentLink Text</a><br /><a class="cssclass" href="documentlink.com/Display?ab=abcd">DocumentLink Text</a><br /></td></tr> 
• URLs in the above HTML text are not being tracked for link click event

We have couple of other dynamic URLs in an  email template derived from email script token  whose click event is not trackable too. Please help us to resolve the issue

Thanks,

Babu
