Trying to replace SecurityAssist generated input field with dropdown menu selection (for "countries" listing)

Hello,

I would like a dropdown list for people to select their country on the on the SecurityAssist generated registration and update pages. The code I currently have in place is:

<tr>
<div class="lineGroup">
<td><label for="Country" class="sublabel" > Country:</label></td>

<td> <input id="Country" name="Country" type="text" value="<?php echo((isset($_GET["invalid"])?ValidatedField("presenterswitchboarddataupdate","Country"):"".$WADApresenter_data_update->getColumnVal("Country") ."")); ?>" class="formTextfield_Medium" tabindex="6" title="Please enter a value.">
</td>
</div>
</tr>

I have on the ready a country dropdown menu selection listing of:

<select id="Country" name="Country" type="text" value="????????" selected="????">
<option value="Afganistan">Afghanistan</option>

blah blah blah
<option value="Zimbabwe">Zimbabwe</option>
</select>
ready to go.

My difficulty is that where I have put the first set of question marks, the current Input field generated by SecurityAssist already has in place:
value="<?php echo((isset($_GET["invalid"])?ValidatedField("presenterswitchboarddataupdate","Country"):"".$WADApresenter_data_update->getColumnVal("Country") ."")); ?>" class="formTextfield_Medium" tabindex="6" title="Please enter a value.">

I am not quite certain if and or where that given precreated input value should be inserted relative to my intended dropdown menu.

I tried inserting the whole, as a replacement, but it would not work.

Thank you.

Where you have the question marks should be removed. That isn't valid for select lists.
