Hello Everyone, I am starting this contest because currently I do not have enough time to work on this problem. The buyer has requested some changes and according to his requirements I have to implement these changes. The winner will get more similar challenges and at the desired price. Read the requirements below and ask if you have any questions. Member "You" is the main member that could register as many members as he want under him. The first two members under You that are A and B. Member "You" will always receive 10% of 6,000 from A and B. It means when "You" will register A and B then he will receive 10% of 6,000 each time so after registering A and B his amount will go to 600+600 = 1200. Member "You" receive 10% of the income of A and B every time so it means if A registers two members then he himself will receive 1200 and member "You" will receive 60 + 60 = 120. After the first two members registered, the member "You" will always receive 25% of 6000 on every registered member so it means if he registers C, D, E and F then "You" will receive 1500 x 4 = 6000. 10% Royalty is reserved for the first 2 members of any member only. In this diagram it is reserved for A and B. When C registers any member then 15% of his income will go to member "You". It means if he registers 4 members then for first members 10% (600+600 = 1200) and for the next two members 25% (1500+1500 = 3000) so the total income of C will be 4200. Member "You" will receive 15% of the income of C so if C makes 4200 then "You" will receive 630. After third member C, for all other members (D, E and F) nothing will go to "You" from the income of these members. I have shown this in the diagram. You can take minimum fields because first you are providing solution to the problem and if your solution is correct and works then I will supply the script where you will have to implement this solution. You can ask if you have any questions. Please PM me if you have any questions. Thanks
