Yes, thanks. The biggest braincloud to disperse is the notion of the dtml-let and dtml-in sequence.

I managed to get it working with this code:

--------------
(this is taken from Amos's articles on xml.com)
-------------

<dtml-let results="findHost(username,password,host,domain)">
<dtml-in results >
<dtml-let X=sequence-item>
<dtml-in X>

<dtml-if sequence-end>
<table border=3 width=70%>
<TR BGCOLOR="#FFFF99">

<dtml-let Y=sequence-item>

<TD width=10%>
        Hostname:   </TD><TD> <dtml-var "Y['Hostname']">  </TD></TR>
<TD >   IP:         </TD><TD> <dtml-var "Y['IPv4Address']">           </TD></TR>
<TD >   Model:      </TD><TD> <dtml-var "Y['Model']">           </TD></TR>
<TD >   Vendor:     </TD><TD> <dtml-var "Y['Vendor']">           </TD></TR>
<TD >   EndUser:    </TD><TD> <dtml-var "Y['EndUser']">           </TD></TR>
<TD >   Room:       </TD><TD> <dtml-var "Y['Room']">           </TD></TR>
<TD >   HostType:   </TD><TD> <dtml-var "Y['HostType']">           </TD></TR>
<TD >   Contact:    </TD><TD> <dtml-var "Y['DNSContact']">           </TD></TR>
<TD >   Remarks:    </TD><TD> <dtml-var "Y['Remarks']">           </TD></TR>
<TD >   TTL:        </TD><TD> <dtml-var "Y['TTL']">           </TD></TR>
<TD >   ORG:        </TD><TD> <dtml-var "Y['ORG']">           </TD></TR>
<TD >   IP Range:   </TD><TD> <dtml-var "Y['IPv4Range']">           </TD></TR>
<TR><TD>  - End of Record-    </TD><TD>     <dtml-var "Y['Hostname']"></TD>
