you could add a javascript onchange event to each of the select lists to populate hidden elements with the selected label
here is an example form that shows how this is done:
<form id="form1" name="form1" method="post" action="">
<label for="select"></label>
<select name="select" id="select" onChange="document.form1.textfield.value = document.form1.select[document.form1.select.selectedIndex].text">
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
</select>
<label for="textfield"></label>
<input type="text" name="textfield" id="textfield" />
</form>
