Can I use control query and Variant?

I tried both but it’s not working, what’s my requirement is in a web template having material, distribution as drop box and I have to create for all countries(Like USA, Canada,China…)so what I did , I created a control query as material& distribution and I created variants for countries. After precalculating it’s not working.

Any help ll be appreciated

Thanks
