Use of the effective Lagrangian incorporating both the scalar and pseudoscalar mesons gives a possibility to calculate the $ππ$-scattering lengths without attraction of the ChPT theory.
Contrary to wide-spread opinion that the final state interaction (FSI) enhances the amplitude $<2π;I=0|K^0>$, we argue that FSI does not increase the absolute value of this amplitude.
