Bounds on invisible decays of the Higgs boson from $tbar{t}H$ production were inferred from a CMS search for stop quarks decaying to $tbar{t}$ and missing transverse momentum. Limits on the production of $tbar{t}H$ relied on the efficiency of the CMS selection for $tbar{t}H$, as measured in a simulated sample. An error in the generation of the simulated sample lead to a significant overestimate of the selection efficiency. Corrected results are presented.
