Simple Componant form

I am building a password protect form, but it doesn’t need to be that secure, I created it and it works, although it is case sensitive, is there a way to make it not case sensitive – here is what is on my submit button –

on (release, keyPress “<enter>”) {
mess=“Sign in please!”;
if (username==“CSI555” ) {
mess=“Invalid password”;
}
if (password==“CSI555”) {
mess=“Invalid username”;
}
if (username==“CSI555” & password==“CSI555”) {
gotoAndPlay(“administrativetools”);

}
}

and my other question is that I want to press the enter key and without tabbing to the button to make it load, how do I do that??

thanks
Ashley
