Self Relationship- not seeing how to get it workin

[fmp7_user_fmp7fmp7]

I have a shipping file that has a record for each customer purchase as follows:

Record 1

Name: joe Smith

Address: 45 J st

Item purchased: widget 34

Weight 5oz

Record 2

Name: joe Smith

Address: 45 J st

Item purchased: widget 57

Weight 10oz

Record 3

Name: joe Smith

Address: 45 J st

Item purchased: widget 16

Weight 5oz

How can I determine the total weight for this customer when all three of the widgets are in separate records?

I think a self join relationship would work somehow, or creating a new record with globals for the weights?? Attached is my work on a script to find the duplicate names I am close but I have hit a wall. Any help would be appreciated. Thank you.

You'd be better of using a relational design for this. Put the customers in one table. Put the item and weight in another table. Link the two using a CustID field (do not use the customer name).

Calculating weight would then be easy... Sum(Items::Weight).
