I have solved this with the following, I hope it may be of help to others:
ZSQL:
select groupabbrev as thisgroupabbrev from pastoralgroup

DTML:
<select name="groupabbrev">
<dtml-in getpastoralgroups>
<option value="<dtml-var thisgroupabbrev>" <dtml-if 
expr="groupabbrev==_.str(thisgroupabbrev)"> selected</dtml-if> 
 ><dtml-var thisgroupabbrev></option>
</dtml-in>
</select>
Thanks for all your help
