Take a look at the Go To Related Records (GTRR) script step. It's a complex step with lots of options to choose, but it can pull up a set of records and change layouts if necessary to properly display them.
If GTRR pulls up a few more records than desired (Such as including Invoice and Quote records), you can then enter find mode and use constrain found set to filter the found set down to the desired set of records.
Great - thanks Phil..will try that out.
Any luck with my printing lines issue from yesterday?
I believe I posted a response, don't remember if I asked a question for more info or suggested a solution.
