I use the iCal script provided as an example on the SMS Mac website

tell application "SMS Mac Scripting"
set m to make new outgoing sms with properties
{flash:false}
tell m
set message to "[message]"
set recipients to {"[tel number]"}
set sender to "[tel number]"
try
send
on error errMsg number errNum
display dialog "Error: " & errNum & ". "
& errMsg
end try
end tell
end tell

This works great when my Mac and iCal are running; script runs, SMS sent, etc.

However if my Mac is off, or iCal is not running, or there's no internet
connection when the SMS script is due to run, then the SMS is not sent.

Can anyone pls help me with edits to this script that "queue" the script to run
as soon as iCal is running and connected to the internet.

Thx!
