Hi There,

I need to calculate the total sum of the hours worked by the hourly cost of each employee that are in two different tables

EMPLOYER
COD_Emp	Cost- Hour
001	$       15.000
002	$       23.000
003	$          4.000
004	$          6.500
005	$       25.000
006	$       12.000
007	$       15.000
008	$       19.000

RECORD
COD_Emp	Hour	Date
008	2,5	1/01/2020
001	1	1/01/2020
007	3	1/01/2020
001	9	2/01/2020
003	4	2/01/2020
005	3	2/01/2020
008	2	2/01/2020
