pdirect,
You can add the File Attachment type field to the customer table and use that to store an attachment. Each File Attachment field that you add can only store 1 attachment per customer, so for example if you want to store 2 attachments per customer you would need to add 2 File Attachment fields. After adding the field you will also need to add that field to you screen to make use of it.
