Solver to get the maximum summary is not working

Hello,

I have a problem with Data Solver, it is not working at all.
I need a maximum of cell U17 and some constraints (green color), by changing cells U3:U14 (red color).



Hopefully there's someone out there that can help!

Here is my excel file

Please post your file on the forum. Thank you
