We have searched for the charmless hadronic decay of (Formula presented) mesons into two neutral pions. Using 9.13 (Formula presented) taken at the (Formula presented) with the CLEO detector, we obtain an improved upper limit for the branching fraction (Formula presented) at the 90% confidence level.
