text box names the same

Hello, I am trying to combine a form I made with text fields that are named "apt" and "number" and "building".  I filled out 38 different forms, all the same and saved them according to their number.  However, when I combine them, of course the fields are all named the same, so adobe changed the fields on all the pages to match the first page!  I do not want to go and rename all the fields.  How can I combine them without it changing all the fields??
