What does the "Data is out of range." error message mean?

I'm running a script with EasyCatalog and I can't figure out what I changed to get this error (or what it's telling me.) Is it script side, file side, both?

It's rather error generated by EasyCatalog - you need to ask them.

Hi Adam:

Could you please share a screen shot of your Pages panel? And tell us if you are using absolute or section numbering (Prefs > General)? Data out of range messages issued on PDF export tend to refer to a page range issue.
