    hi,
    i have this table
    Emp Sum_sales Manager Child
    10 0 Null 0
    11 130 10 1
    12 260 11 2
    13 0 12 3


    the number of children is not limited.

    i need to calculate the comm of the employees: the result should be like that:
    emp10=(sum_sales of emp 11 * child 1 perc)+(sum_sales of emp 12 * child 2 perc) + (sum_sales of emp 13 * child 3 perc)

    emp11=(sum_sales of emp 12 * child 2 perc) + (sum_sales of emp 13 * child 3 perc)

    emp12 = (sum_sales of emp 13 * child 3 perc)

    how should i write the script to get this result ur help is really appreciated

    best regards,
    Roger
