its a typo. they meant to use '=' not '-'

I GOT IT! THANK you

and is this line " $msg: $msg2"  also a typo. i found there is no value  given to variable $msg。

[mikesta707]

there should be... its the parameter of the function. when you call the function you are supposed to set the value of that variable

[RussellReal]

this

echo <<< _END

 

should be

 

echo <<<_END

 

and inside this you should be able to do $msg: $msg2 because : isn't a valid character for a function name
