Customers must have a unique ID (customerID?) Projects must have a Projects:customerID number field. The two need to be related.
Is there a way to do this? If so could someone help me as this is a new program to me and I am still trying to get used to it. Thanks!
To relate them, make sure you have customerID fields in both tables. Use Manage | Database | Relationships to link them by CustomerID if they are not already so linked.
If you imported your customer contacts from an external file, it's very likely that the imported records do not have a customerID unless such a field was already defined in the table and you enabled auto-enter options (a check box that appears in the very last dialog to pop up before the import starts) for the import.
