Why not copy the PDF text onto a layout so that you can PDF the Purchase Order and this additional information in one step from the same layout?
This need not be the layout your user sees. When you click a button to save a PDF of it, the script can switch to this other layout to save the PDF then switch back.
Fantastic idea. I don't work at all with Filemaker layouts but we have someone on site who does occassionally work with the layouts of our files and she offered a similar suggestion. The question she has is how to expand the page size of the layout.
I can read Page size several ways.
The "page size" (shown by page break lines in layout mode) of a layout is determined by the settings in Print Setup. To move the page break lines, just select a different page size or orientation in that dialog. (You can use print set up to select those options in a script just before you do a save as PDF also.)
Layout Parts such as a Header or Footer where you might include this information can be made larger by dragging their borders up and down.
Actually, yes, I noticed that in layout mode, you can drag the BODY button down and that will add more pages based on page size. I think that might do it for us. Thanks again for your advice!
