comparing attribute to a variable

I am creating an order form for work where you can add and remove rows with javascript. The issue I am having is after the most recent row has been removed I cannot add a new row.

I have a variable called rid which increments each time a row is added. I need to check the row to be deleted's id against the rid, if they are the same then it needs to lower the rid by one. I assume the issue is that the attribute and the variable are different types of string. The new rows are added using $('#tr'+rid).after()

$('div.remove').live("click", function(){
        id = $(this).attr('id').replace(/r/, '');
            if(id === rid){
                rid = rid-1;
                alert(rid);
            }
            $('#tr'+id).remove();
});

you should cast $(this).attr('id').replace(/r/, '') to an int value:

var id = parseInt($(this).attr('id').replace(/r/, ''), 10);

that should work
