Trouble with new onlinemapsources.xml

I'm trying to add MyTopo.com maps to the OruxMaps app. I'm having issues with the configuration. I'm wondering if anyone can help out.

I pulled this URL string with an HTTP debugger: http://tileserver.mytopo.com/SecureTile/TileHandler.ashx?mapType=Topo&partnerID=12288&hash=22EE40F371EBDEDCE074D34F8395BC83&x=85&y=186&z=9

I modified the onlinemapsources.xml file with this added new information:

<onlinemapsource uid="20">
<name>MyTOPO</name>
<url><![CDATA[http://tileserver.mytopo.com/SecureTile/TileHandler.ashx?mapType=Topo&partnerID=12288&hash=22EE40F371EBDEDCE074D34F8395BC83&x={$x}&y={$y}&z={$z}]]></url>
<minzoom>9</minzoom>
<maxzoom>16</maxzoom>
<projection>MERCATORESFERICA</projection>
<servers></servers>
<httpparam name=""></httpparam>
<xop></xop>
<yop>0</yop>
<zop></zop>
<qop></qop>
</onlinemapsource>

Does anyone know where I'm going wrong? Thanks!

Is Orux around to answer questions? Haven't had any response on this question yet.
