updates to two projects php and xml

Project only for HIUKIM. Henry...im looking for an update on the last project. The add and delete buttons add and remove the last text field and paramter field to the form. Im trying to see if its possible to add a radio button or similar to each item. So if the radio button is checked and you add a node it will create a new text fild at that point..moving everything down but automatically changing the following parameter fields by 1. equally delete would revomve that node and each paramter would be reduced by one. Also update on previoud project from a while back. I'll DM you the details
