I would like to combine two PDF files: one is a form created with Adobe. Here, the final text field is calculating the sum of all fields from above. The second one is a regular PDF, no form. When using Ghostscript, the form disappears. With pdftk, in the combined PDF the form page still has the text fields, but no sum is calculated.
Any ideas which programs (or options with pdftk) I can use to combine a PDF form that has a calculating field in it and is maintained in the final PDF? I have to do this with about 200 PDFs, so a batch process is needed.
Thanks for any suggestions!
