AppleScript access to other columns?

[Jim Miller]

I've got a to-do list type outline that has a "Priority" column in  
it; this has pop-up list entries like "Today", "Tomorrow", and so  
on.  I'd like to write a script that gets all the rows whose priority  
column is "today" (for instance), but I can't figure out how to get  
this other column data for the rows.  Any suggestions?

Thanks,
Jim MIller
