For debugging, change your script to be <small><font
face="FreeMono"><a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://localhost/arqueoserver3/OpenLayers-2.12/OpenLayers.js">http://localhost/arqueoserver3/OpenLayers-2.12/lib/OpenLayers.js
</a><br>
It will then use an uncompressed version of openlayers and you
can see more clearly what is going wrong.<br>
