hi experts

I am using EXT-Js 4.2 code to design some UI for my project.

I have set a renderer in my javascript code for a grid column

function firstnameRenderer(val) {       
if(same firstname occurs twice , then color the two firstname with orange){ 
return '<span style="color:orange;">' + val + '</span>';	
    return val;
        xtype : 'grid', 
        stripeRows: true,
        title: 'User Information',
        store: Ext.data.StoreManager.lookup('mystore'),         
        autoHeight: true,
        plugins: [ cellEditing ],
        columns: [            
            {header: "First Name", width: 100, dataIndex: 'firstname', renderer: firstnameRenderer, sortable: true}

I want to check if a same firstname appears twice, if yes color it with orange.
Any idea how firstnameRenderer() function above should change ?
