GridPanel Woes...

[Phunky]

I seem to be having a lot of problems with GridPanels at the moment i cant get the following to work

new Ext.grid.GridPanel({
							region: 'center',
						    store: data.referrals,
						    columns: [
						        {id:'company', header: "Company", width: 200, sortable: true, dataIndex: 'company_id'},
						    ],
						    viewConfig: {
						        forceFit: true
						    },
						    sm: new Ext.grid.RowSelectionModel({singleSelect:true}),
						    frame:true,
						    title:'Framed with Checkbox Selection and Horizontal Scrolling',
						    iconCls:'icon-grid'						
						})

The above code produces the following error

[app:/main.html][09:58:06] TypeError: Undefined value

hmmm it would seem that it didnt like my store being in data.referrals :S had to remove it from data and just make its own var
