I was looking at the code linked above...it looks odd, and I'm assuming that's the case, because it seems to be an rtf document rather than a plan text html file. You may want to save it as plaintext. Either way, can you change the values of the dropdown menu? Here's the code you have currently: <select class="head1" name="attr_Campaign_Type" style+"width:74%">
<option value="">Choose a Campaign Type</option>
<option value="campaign_normal">Normal</option>
<option value="campaign_heroic">Heroic</option>
<option value="campaign_superheroic">Superheroic</option>
</select> Can you change it something like this: <select class="head1" name="attr_Campaign_Type" style+"width:74%">
<option value="0">Choose a Campaign Type</option>
<option value="1">Normal</option>
<option value="2">Heroic</option>
<option value="3">Superheroic</option>
</select> Once you do that, you can have a checkbox with the name='attr_Campaign_Type' with the value=1, then when the dropdown has Normal selected, the checkbox will automatically be checked, and then you can use that to hide/unhide the additional tab. If you want to see how I did it, you can view the Savage Worlds Tabbed character sheet. I hide the Vehicles tab and the Arcanum tabs based on things in the configuration section.
