Hi

I am new to filemaker, I am trying to update qty in stock as I sell items in invoice by press update button -- set field in stock,qty_in-stock calculate result " Extend ( stock::qty_in_Stock )-Invoice::qty" -- only updates 1st entry not repeated fields.

stock qty_in_stock is not a repeating field

I appreciate your help
