jQuery Grid Plugin - jqGrid

I'm new to jquery/ jqgrid.  I've got the basic grid working with my data but I'm stumped on providing extra filtering to my CFC.  I need to pass in extra variables [myacct] to the query besides the grid info.  I don't know where to put the variable in the grid.

This is my grid:

 <script>
 $(document).ready(function()
  {
   $("#list").jqGrid(
   {
    url:'Users.cfc?method=GetAllCases', //CFC that will return the users
    datatype: 'json', //We specify that the datatype we will be using will be JSON
    colNames:['ID','Case Number','Site ID','Site Name'], //Column Names
    //The Column Model to define the data. Note you can make columns non sortable, specify width, alignment, etc.
    // [#objid#,#x_account_id#,#x_site_id#,#x_site_name#]>
    colModel :[
     {name:'objid',index:'objid', width:50, sorttype:"int"},
     {name:'x_object_id',index:'x_object_id', width:150, sorttype:"string"},
     {name:'x_site_id',index:'x_site_id', width:150, align:"left",sorttype:"string"},
     {name:'x_site_name',index:'x_site_name', width:150, align:"left",sorttype:"string"}
     //{name:'UserName',index:'UserName', width:150,align:"left",sorttype:"string"},
     //{name:'UserAccountingCode',index:'UserAccountingCode', width:150, sortable:false},
     //{name:'Phone',index:'Phone', width:150, sortable:false}
    ],
    pager: $('#pager'), //The div we have specified, tells jqGrid where to put the pager
    rowNum:20, //Number of records we want to show per page
    rowList:[4,8,12], //Row List, to allow user to select how many rows they want to see per page
    sortorder: "desc", //Default sort order
    sortname: "ID", //Default sort column
    myacct: "268440464",  // my account
    //myDSN: "ClarifySMST", // pass in required vars
    viewrecords: true, //Shows the nice message on the pager
    imgpath: 'themes/coffee/images', //Image path for prev/next etc images
    caption: 'Open Cases', //Grid Name
    height:'auto', //I like auto, so there is no blank space between. Using a fixed height can mean either a scrollbar or a blank space before the pager
    recordtext:'Total Records', //On the demo you will notice "7 Total Records" - The Total Reocrds text comes from here
    pgtext:'of',//You notice the 1/3, you can change the /. You can make it say 1 of 3
    editurl:"Users.cfc?method=GetAllCases",//Not used right now.
    toolbar:[true,"top"],//Shows the toolbar at the top. I will decide if I need to put anything in there later.
    //The JSON reader. This defines what the JSON data returned from the CFC should look like
    jsonReader: {
     root: "ROWS",
     page: "PAGE",
     total: "TOTAL",
     records:"RECORDS",
     cell: "",
     id: "0"
     }
    }
   );   
   
  }
 );
 </script>

This is my CFC:

 <cffunction name="GetAllCases" access="remote" returnformat="json">
     <cfargument name="page" required="no" default="1" hint="Page user is on">
     <cfargument name="rows" required="no" default="15" hint="Number of Rows to display per page">
     <cfargument name="sidx" required="no" default="" hint="Sort Column">
     <cfargument name="sord" required="no" default="ASC" hint="Sort Order">
        <cfargument name="myacct" type="string" required="yes" hint="Biz Org to get "> 
         
     <cfset var arrCases = ArrayNew(1)>
          
  <cfquery datasource="ClarifySMST" name="get_cases">
   select objid, x_object_id, x_site_id, x_site_name
              from SA.TABLE_X_PORTAL_OBJECT
             Where  x_bus_org_objid = <cfqueryparam cfsqltype="cf_sql_integer" value="#myacct#">
             

  </cfquery>
       
          <!--- Calculate the Start Position for the loop query.
  So, if you are on 1st page and want to display 4 rows per page, for first page you start at: (1-1)*4+1 = 1.
  If you go to page 2, you start at (2-)1*4+1 = 5  --->
  <cfset start = ((arguments.page-1)*arguments.rows)+1>
  
  <!--- Calculate the end row for the query. So on the first page you go from row 1 to row 4. --->
  <cfset end = (start-1) + arguments.rows>
  
  <!--- When building the array --->
  <cfset i = 1>
  
 
  <cfloop query="get_cases" startrow="#start#" endrow="#end#">
   <!--- Array that will be passed back needed by jqGrid JSON implementation --->  
   <cfset arrCases[i] = [#objid#,#x_object_id#,#x_site_id#,#x_site_name#]>
   <cfset i = i + 1>   
  </cfloop>
       
    <!--- Calculate the Total Number of Pages for your records. --->
  <cfset totalPages = Ceiling(get_cases.recordcount/arguments.rows)>
  
  <!--- The JSON return.
   Total - Total Number of Pages we will have calculated above
   Page - Current page user is on
   Records - Total number of records
   rows = our data
  --->
  <cfset stcCases = {total=#totalPages#,page=#Arguments.page#,records=#get_cases.recordcount#,rows=arrCases}>
  
  <cfreturn stcCases>

  <!--- <cfreturn get_cases> --->  
 </cffunction>

Firebug error is that the variable is not declared.

How do I do this?

Thanks,  Jim
