got it
the form for the yahoo maps in the above files should be changed to
<form name=mapForm2 action="http://www.multimap.com/map/browse.cgi" target="_new" method=get>
<input type="hidden" name="pc" value="<{$link.zip|replace:" ":""}>">
<input type=submit name="getmap" value="Map">
</form>
and change the template in the manager to make it all work.
