No, that wouldn't cause the problem.
In your form template, the call for the drop down should look something like this, does it?
Code:
<td class="alt1" valign="middle">
<b>$dropdownquestion2</b>:
</td>
<td class="alt1" valign="middle" colspan="2">
<select name="dropdownanswer2">
<option value="$dropdownchoice2a" <if condition="$dropdownchoice2a == $dropdownanswer2">selected="selected"</if>>$dropdownchoice2a</option>
<option value="$dropdownchoice2b" <if condition="$dropdownchoice2b == $dropdownanswer2">selected="selected"</if>>$dropdownchoice2b</option>
<option value="$dropdownchoice2c" <if condition="$dropdownchoice2c == $dropdownanswer2">selected="selected"</if>>$dropdownchoice2c</option>
</select></td>
</tr>
