You need to tell the app where you move the fields. This can changes things with relationships also, so you will need to verify your relationships. The field with the missing table just double click and then select the new location of the field. Go to File then manage layout and then select edit on any layout affect by those field and besure that the the correct field is "show records from". Any scripts that refers to old location of file will have to be verified. We all do these type mistakes when we are learning. Remember you can make backups with save copy as, which is a good idea every 15 minutes or so when you are working on a large project. Good Luck.
