PHP expert needed to analyze code

A mid-level PHP coder at PeoplePerHour has not been able to identify the PHP code that takes input data and then does math calculations on it. He has said OK for me to hire an expert for this, while he does simpler revisions on the code.

A typical working page after data collection is at http://www.social-quotient.info/socialquotient/setup/results/first/a60f7aa1e5b3c2b0be29eb4a5c066564 . After the math calculations, a formerly working page looks like this screenshot: https://prnt.sc/duw5nb. The trigger to start the calculation will be an upcoming Saturday date, which you will connect to the missing code.

You will be given access to the mostly working code at Hostgator.com and the full cooperation of the mid-level coder. The original creator of the code is unavailable. Deposit of up to 50% of the fixed price contract.
