Inserting a Hyperlink in a workflow-generated email

I have a simple workflow in which I generate an email.  I want to insert a hyperlink into the email that contains a field to be dynamically inserted, but it is not rendering correctly.  Here are two methods that I've tried without success:

In this first example, the markup text shows:
example: 

<a href="http://www.nysar.com/somestuff/{Course(Class (Class))} ">Click here to get your student workbook</a>

RESULTS

 <a href="http://www.nysar.com/somestuff/RI407-Build Your RE Pract ">Click here to get your student workbook</a>

 In the SECOND example, I only get the NAME text:

<hyperlink><name>TEST TET TEXT</name><value>www.nysar.com/{Course(Class (Class))}</value></hyperlink>

RESULTS:

TEST TET TEXT
