I have a PDF that I need to remove all pages except for the last one. The PDFs will vary in page sizes making it impossible to manually set the pages to remove.

I've created a get information task and am pulling the number of pages.

I can then use the output in a remove pages task to remove 2-output so I'm left with the first page. This works great.

Any combination of formulas I've tried to remove pages 1-(output-1), doesn't work.

Is it possible to modify the output with a formula? or is there another solution to only save the last page of a PDF?

Of course as soon as I posted this, I figured it out. Here's the solution for anyone looking:

1) Create a user defined variable with type int32
2) Create a calculate variable task. Store it in the user defined var from step 1. Left hand value = output from your get information task. operation subtraction. right hand value = 1
3) use 1-[uservar from step 1] in your remove pages task.

Great solution, thanks for the contribution!
