I have a form that is triggered at the beginning of a Forms List. Further down the Forms List is another form that is triggered and it is made up of many sections.
There is a section in this last form where I need to reference its page number in the first form. Is this possible with DM11.5 single step?
The issue will be whether you are trying to query this during print, since I don't think the page numbers are assigned until the print begins. If so, then you could simply add one of the appropriate system page fields on the section and then you can query it using DAL.
If you are not trying to do this during print, then the page may not be determined unless final pagination has occurred - which normally is not until the final transaction rule (PaginateAndPropagate). In this case, you would have to be more brute force as querying the page number field would not help since you are not in print. So, I think you would be relegated to looping through the pages using the PageImage() function and ImageName() using the number parameter to keep moving forward on the page and testing the name for the section that you are looking for.
