Solver is not solving

Hello,

I have a problem concerning below task.

Task description: Factory produces three products, but only two products can be produced in a one day. Production capacity is 2100 ea per day. The ratio of one product’s daily production quantity to another must be 1:2, 1:1 or 2:1. Weekly raw material availability is limited and shown in the table. It’s necessary to make production plan maximizing production capacity usage.

I decided to solve the task by Solver. I've made the model as in the attached file, but it doesn't do anything.

Please help, whether my model is not correct or there is another way (not Solver) of solving!

Thank You!
