Hi, Eric,
to get the solution for your problem do the following steps:
go to the MySQL Homepage (www.mysql.com) you will find a search field to the left. Enter 'dump' in it you will get a result of your search click on the first link of the result locate the line "You can read this back into MySQL with..." The MySQL Manual is a great source of information for problems of this kind. You will get it much quicker and more detailled, if you search there first, before you post here.
good luck
