State missed call will only go active the first time you miss a call,
until you clear the calls. You should use Event missed call, which
fires each time you miss a call.
However, you want to send the 'available now' texts when all calls are
cleared, so you've attached that to the correct context as it stands
(exit task of state missed call).
In sum:
Event: Missed Call
Enter Task: 'not availableable SMS'
State: Missed Call
EXIT Task: 'available now SMSs'
Second thing:
> Messaging App:On ] If [ %BUSYTM < %TIME ]
You may be using this incorrectly. You're comparing mathematically
something like '3.15' and '17.15'. Remember, after 23.99, %TIME will
become 0.00. Depending on what you want to achieve with the
comparison, you may be better using %TIMES (see varaible section of
userguide).
