System and server status

Can you not use the if else statements for sms messages? When saving the e-mail template I don’t receive any errors, but upon checking the e-mail template again I find that the sms message only has the first line of my if else statement. (as listed below)

(What I have entered and saved in e-mail and SMS boxes)

Network traffic on ${HOST} has exceeded 50mbps
Network traffic on $(HOST) is no longer above 50mbps.

(What gets saved in my sms box)


Any suggestions or ideas or does this simply not work for sms messages?
