input text box: Multi vs Single Line

[Akimbo_Jones]

Hi there
I need to create a multiline input textfield. The following code works for single line, but not multiline. What can I do?

[actionscript 3, CS4, PC, ("p1empty" and "p1compare" are frame labels)]

on (release){
if (input1.text == ""){
gotoAndStop("p1empty");
}else {
gotoAndStop("p1compare");
}
}

THANKS!
