HTML import button of tasks uses predecessors numbers not in the database

I followed Steve Smith's instructions ( here http://www.quickbase.com/quickbase-blog/how-to-quickly-create-multiple-child-records-in-quickbase ) and it worked like a charm until i created tasks with predecessors.  When I do that, then the original predecessor number is imported, and within the task i get an error that that number doesn't exist within the database.  Is there a way to fix this?
