jQuery Grid Plugin - jqGrid

Ok, I have tried this multiple ways and I still can not render any data into the grid.  I know that jqgrid is finding my xml file because firebug says so and also my column names are being rendered.  I have tried each version in both FF3 and IE7/8 with same result.  Can someone tell me what I am doing wrong??

script for jqgrid:

$('#searchResults').jqGrid({
url: 'weaponLib/chemTest1.xml',
datatype: 'xml',
colNames:["DODIC","NSN","Nomenclature"],
colModel:[
{name:"dodic",index:"dodic",width:15,xmlmap:"chemicals>chemical>dodic"},
{name:"NSN",index:"NSN", width:180,xmlmap:"chemicals>chemical>transData>NSN"},
{name:"nomenclature",index:"nomenclature", width:100, align:"right",xmlmap:"chemicals>chemical>nomenclature", sorttype:"float"}
],
autowidth: true,
rowNum:10,
rowList:[10,20,30],
viewrecords: true,
loadonce: true,
xmlReader: {
root : "chemicals",
row: "chemical",
},
caption: "Chemical Weapon Results",
pager: '#gridNavBar'
});

I have tried it with a xmlReader id and without an id.  I have tried stating the whole xml map, but jqgrid tells me that the number of colNames does not match the number of items in the colModel.  I reworked my xml structure so that the id was associated with a element that I would never display.  I also removed all of the element attributes and made them their own elements (so that I can later change between metric and english measurements).

So what gives????

Here is my xml model:

<chemicals>
<chemical chemId="1">
<dodic>k866</dodic>
<weaponType>smoke</weaponType>
<nomenclature>Smoke Pot: HC, 30-Pound, ABC-M5</nomenclature>

<use>To produce screening smoke for training exercises and demonstrations, but can also be used in combat.</use>
<description>The ABC-M5 smoke pot is a cylindrical sheetmetal container, filled with about 30 pounds of slowburning, type-C, HC smoke mixture and 1 pound of fast-burning, HC smoke mixture. A carrying handle is mounted on the outer cover.</description>
