Scratch

Well yes, there is a method. This one works if you haven't used any ask blocks yet:

when gf clicked
set [Answered? v] to (1)
broadcast [Broadcast v]
wait (5) secs//The wait.
if <(answer) = []>//This is a blank.
 set [Answered? v] to (0)
 broadcast [Broadcast v]
end

when I receive [Broadcast v]
if <(Answered?) = (1)>
 ask [What do you want to say?] and wait
end

Now, if (Answered?) equals 1, then that means that they answered you, but if it equals 0, then that means they didn't.

Also, if you need to use this more then one time, or need to use it after other wait blocks, then just ask me for the other script seeing as this won't work in those situations.
