So i've got this database i have to make for business studies and i'm stuck as to how you delete the relationships for the tables 
anyway in the tables i have i need to change the primary keys from text fields to autonumber fields to do this it states that i have to delete the relationships i made for the tables so i do the clear layout ...doesnt work..... i then used the delete button found on the home tab for each table..... still doesnt work..... how in the hell do i delete the damn relationships its really preventing me getting any further and is driving me up the wall
by the way its Microsoft Access 2007
Thanks
Leon
