If a script saves various layouts to a combined pdf in the temp folder, how do you pick that pdf up to open it.....??

The only way I can see is to set the last Layout to open the file... However if you have 10 layouts all of which may or may not be printing to the current pdf how do you pick that pdf up AFTER the last layout has printed :

The only way I can see is a load of scripting to ascertain which layout will be the last and use "if" statements throughout the process....

maybe there is another easier way :

For instance if you want to send an e.mail you can pick up the resulting pdf and e.mail it....

I cannot see a way to pick up a resulting pdf and open it AFTER the last layout has saved to it.....

Am I right ?

Well, you know the path to the pdf, right?

Probably something like:

"file:" & Get (TempPath) & "myfile.pdf"

You could use Insert File script step, with the path to put it in a container field and then open it.
