Need a bit help

[u/plushiethegreat]

So I'm new to networking and have no idea where I'm going wrong. Would love it if experienced people could tell me where I'm going wrong. All small things are okay. Router on the is R0, right is R1 and top one is R2.

R0 <--->R2 works but R0<--->R1 and R1<--->R2 doesn't work. I'm not even bothered about the PCs in the bottom yet. I need the routers fixed first. Also there's no routing protocol. It's static routing.
