BTW, I looked at your other dropbox and it's coded wrong. Each option needs to look like this:
<option value="law">Books of Law</option>
<option value="his">Books of History</option>
<option value="wis">Books of Wisdom</option>
<option value="map">Major Prophets</option>
Instead, you're trying to nest options inside other options by putting all of your </option> closing tags one after another.
In case you've tried that dropbox for what you're doing, that won't work because that one has all of the options leading to the same page. The values in those <option> tags become variables on the destination site, which gets inserted into a script to show the correct results.
In contrast, you need a form like the one I linked to above, because you want each <option></option> to go to a different page entirely.
