I am trying to create an email template where a section of the email only appears when a drop-down list has a certain value (e.g. lead source is not website).  See my code below.  Can anyone tell me why my IF statement is not working here as the section is always appearing in the email?

<table>
<tr align="left">

<td width=35%><font face="Arial" size="2">{!Lead.Company}</font></td>
<td width=15%><font face="Arial" size="2" color="#38ACEC"><b>Company Website:</b></font></td>
