If a person enters a Shul, and hears the tzibbur saying “yehei shemei rabbah…..”, he should join them and respond “yehei shemei rabbah…”; he should not say the amein before yehei shemei rabbah unless the congregation is saying amein, and he is able to think about the previous phrase to which it refers.
