Here's a little jQuery that prevents non-numerical inputs:

$(function() {
    $('input').bind('keyup', function(event) {
        var currValue = $(this).val();

        if(currValue.search(/[^0-9]/) != -1)
        {
            // Change this to something less obnoxious
            alert('Only numerical inputs please');
        }

        $(this).val(currValue.replace(/[^0-9]/, ''));
    });
});
