nearly there but not quiet

Hi I have got so far with my form below

I have now realised that if a customer wants to order for more that 1 window which is highly likely they need to be able to go through the process as many times as they need adding for each window and then it needs to total the whole order up at the end. 

Is that possible?

I believe you were responding to the original thread about this here

I suggest you update us on that thread instead to avoid confusion.
