Hello! Sorry to be bothersome but I've been trying this piece of code and I can't figure out why it isn't working.

parameters = {a -> 0.5, b -> 1.5}
solution =
NDSolve[{u'[t] == 1 - (b + 1) u + a u^2 v, v'[t] == b u - a u^2 v,
u[0] == 0.0, v[0] == 0.0} /. parameters, {u[t], v[t]}, {t, 0,
200}]

I get the following error:
NDSolve::dvnoarg: The function u appears with no arguments.

None of my friends are familiar enough with Mathematica to help. I'd really appreciate any guidance! Thank you!
