codigo erroneo

[elogius]

Ayuda por favor, cuando intento poner mas de un password válido no me hace caso. Donde está el error? Os adjunto mas abajo la versión inicial que funcionaba bien (pero con un solo password).

Muchas gracias.



function password() {
var testV = 3;
var pass1 & pass2 & pass3 = prompt('Estimate Agency , enter the password that provides you. Thank You','');
while (testV < 3) {
if (!pass1)
if (!pass2)
if (!pass3)
history.go(-1);
if (pass1 == "ES589221" & pass2 == "ES345671" & pass3 == "ES328661") {
alert('Welcome, you can view the booking now');
window.open('booking.htm');
break;
}
testV+=1;
var pass1&pass2&pass3 =
prompt('Denied Access - Wrong Password, Try again please.','Password');
}
if (pass1!="ES589221" & pass2!="ES345671" & pass3!="ES328661" & testV ==3)
history.go(-1);
return " ";
