I forgot to mention that each PDF for each record will have a different name.
Thank you for your post.
Export is not possible in Instant Web Publishing (with FileMaker Pro 8.5, 9.0 and 10.0). With FileMaker Pro 8.5, when you create/edit your script, there is a checkbox in the lower left corner for "Indicate web compatibility". Check this box and you will see all script steps available for Instant Web Publishing.
Is there no way around this like with a plugin or something? I mean, I know how to get around it but it would mean adding another field and attaching the same PDF again (but as a link instead of as an image (Insert File as opposed to Insert Image)) thus making the database twice as porky.
