That worked nicely.

$().ready( function()
{
    $("form.BUYITBELOW:has([name='itemquant'][type='text'])").each( 
function()
    {
         $(this).validate(
        {
            rules: {
                itemquant:
                {
                    required: true,
                    digits: true,
                    minLength: 2
                }
            },
            messages:
            {
                itemquant:
                {
                    required: "Please enter a qty",
                    digits: "Qty must be a number",
                    minLength: "Qty must be at least 2 digits"
                }
            }
        });
    });    
});


Thanks.
