If I understood you correctly, the code you are looking for should look something like this:

var values = document.querySelectorAll('input.amnt'),//find all inputs  
                                                //that you need to add 
                                                //use regular dom selector 
                                                //like in css
    subtotal = 0;

for(var i = 0, ; = values.length; i

It'll always add all the vales in the documents, you can add or remove data, doesn't matter.

PS please do not use

tag - it's deprecated, you should be using css for that.
