Its hard to debug just a picture - always attach your worksheet, too, (and state which version of Prime it was created with).

The error message is not really helpful.

 

When you look for "odesolve", the help states

"The ODEs must be linear in their highest derivative term"

which is not the case in your example (ya'^2), but I am absolutely not sure if this really is the cause for the solve blocks failing. Actually I doubt that thats the problem as the error message does not change if I delete the square operator in ya'.
