In this talk we will have a brief look at the two decay modes $B^0_s \rightarrow J/\psi \phi$ and $B^0_s \rightarrow\psi(2S)\phi$ and the measurement of the corresponding ratio. To guarantee identical topologies between the two decays we have chosen to only look at the $\psi(2S)\rightarrow \mu^+\mu^-$ and $J/\psi \rightarrow \mu^+\mu^{-}$ modes. A quick look at the peaking backgrounds $B^0_s \rightarrow J/\psi f_0(980)$ and $B^0_s \rightarrow\psi(2S)f_0(980)$ is also given attention.
