JQuery :: Adding Totals In Repeat Table Row

I have a table that has a textfield for inputing numeric values. This field is in a repeated row table. The field id is 'amount'. I want to add all values in the text fields with ID 'amount' and display the sum in a textfield called 'totals' which is in a seperate table but in the same form. I have limited experience with jquery and I actually managed to create and delete a table row from reading posts on stack overflow. I tried using each() but it only works with the first row which is the default row.

$("#addrow").click(function(){
alert("It works.");
//$('#description tr:last').after('<tr>...</tr>');
$('#description tr:last').after('<tr><td align="center"><label for="description"></label><input name="description"type="text"style="background-color:#CCC;"

[Code].....

However as stated, It only works with the first default row that was loaded with the html. Values I input after adding a row using jquery doesn't get summed up.
