I have worked on this code for a week, as to not have to ask for assistance but i cannot find the problem with the code, so here goes I have a series of if and elseif statements that change two variable outputs $costs and $change. They are not working properly. i have attached the code.

this runs through a while statement and collects anywhere from 20 to 1,200,000 records (it runs no problem but the change and the cost do not come out they way they should)
any help would be greatly appreciated
