Yet Another Mysql Problem

Hi again, I've run into a nice bug using phpmyadmin to import data into a mysql database, and was hoping someone had some experience with doing this. I was wondering if there is any common errors which could be occurring due to characters with in the data? I'm fairly certain that this is the case as I can import about 5 lines of the database in mysql through phpmyadmin, and these don't have many odd characters in them, but anymore and it turns around and gives me an error, any ideas? Steve.
