[Solved] Scripter ll or lll if you have time

Hello, 

I'm having some structure issue which exceeds my logic

Maybe it's easy to solve for somebody more experienced:

 

Breakdown

RequestInputDto consists of 3 client input fields 

PriceIndication consists of about 12 variables.
These variables need the RequestInputDto's data for all of them to be calculated. 
After that, the PriceIndication output must be returned to json

Im a little lost on where to catch what and calculate who.. something like that

Please reply question if you need more info
Or reply clarification maybe

Thanks in advance,
