Ok, more detail:
I have 2 tables
Client table: that stores client information and the established costs, each client can have different costs.
Job table: table where the jobs performed are recorded with the respective details and the final cost.
For example, customer A asks for several services to be performed:
Service 1
Service 2
Service 3
The prices of each service for customer A are in the customer table.
What I am looking for is that when filling in the form in the job table the respective customer (Customer A) to be able to use the costs set for that specific customer that are in the customer table and thus automatically calculate the final price.
Attached are the test tables I have worked with, the forms.
The formula I want to propose for the final price is
Precio final = Precio 1*Cantidad de operaciones 1 realizadas
