Need help working with the array output by getDocumentChildren API function

I figured it out! As usual, I was making it way too complicated. What I really needed to do was run some php from the template variable on the subpage being called by Ditto on the main page. So, using @EVAL, I was able to identify the current page and use it as the base for the second Ditto call. It works perfectly!

I don’t know if this makes sense or is useful to anyone outside of the project, but regardless, thank you for all the help.
