saving a second PDF to the server

Hello there,
I am using the hook “add_action( ‘gfpdf_post_save_pdf_9…” to generate a copy of a PDF to my server. It’s working well. But when I want to add a second hook “”add_action( ‘gfpdf_post_save_pdf_40” to generate a copy of a PDF from another form, the PDF is not appearing on my server folder.
Any idea?
