ADVANCED VBA-SKILLS NEEDED, Deadline in 6 days: Rewrite an existing VBA-code by adding one variable and adjusting the code to it

I have an already functioning VBA-code, which hast to be modified to fit an other case. A new variable hast to be added, which also affects already existing variables. The VBA-skills you need do not have to be very advanced, but you need enough experience in programming because understanding the problem is pretty hard. You also would have to work with a program called open solver. But when you look at the open solver-part in the existing, functioning tool you should quickly understand how it works. The VBA-programm consists of 3 optimization steps. I already changed the first step so it fits my case (and it works). Step 2 still has to be changed, this is your task! I am not interested in step 3, you can ignore it. I guess it takes one days for really understanding the tool and two days to change the second optimization step, so it takes 3 whole days in total. !!! My conditions !!! -I need the solution on Thursday 21.12.2017 18:00 (French time) in the evening and not later. So you should finish a functioning version until Thursday Morning so you can still make a few adjustments until the deadline in the evening in case it is necessary -I wont pay you anything, if a correctly functioning code is not finished by Thursday 21.12.2017 18:00 (french time). So please consider if you have enough time! -But: For every day you can finish it earlier, you will get 25€ more. -I have to be able to understand what the tool does. Please make sure, that you write enough comments into the code so I understand what you did. (comments have to be written very detailed, my VBA-skills are very basic)
