[I tried to make a macro to trigger a series of actions in succession, but I got an error message.]

Commands relating to speech (i.e. the "/say" function) cannot be executed simultaneously with other actions. You must provide a break between actions before setting another action, otherwise an error will occur and the macro will not execute properly.

[I tried to enter another line of text right after sending the previous one, but I got an error message.]

If you try to enter multiple lines of text very quickly within a certain period of time, an error will occur and the text will not be spoken.
