Arduino with 2 load cells (3 wires)

I'm new with load cells, and I have problem with my project, using 2 load cells with 3 wires is hard to get reference, many people using 4 load cells with 3 wires or using 4 wires load cells, can you help me?

I use that schematic, is it right ?

But I always get same numbers.
