Wow.. If you downloaded 1.50 before this post redownload... I left out one of the most important parts of the hack... If you've already installed it's just a template edit so do this:
Find:
Code:
<!-- / subject field -->
Add Under:
Code:
<!-- department -->
<tr>
<td class="smallfont" align="left">$vbphrase[department]:</td>
</tr>
<tr>
<td align="left">
<select name="departmentid">
$departmentselect
</select>
</td>
</tr>
<!-- / department -->
Sorry about that guys. If you don't want to do this you can upload the install script and just click on the link that says install templates and it will update the template for you!
