Change of script for password protect file

[Shona]

Hi

Hi

I have this script but when the person puts in the correct password it comes
up with correct password and they have to click OK does anyone know which
part of this do I remove to save them having to do this

var Pw = document.pass.protect.value
if (Pw=="null")
{pass_protect=0}
else
{
i = 0
while (i < 3)
{
switch(Pw){
case passwords :
alert("Correct Pass")
window.location="http://www.file.asp" ;
//Change the html file above
pass_protect = 1
//Change the html file above
break ;
}
i = i + 1
}
}
if (pass_protect==0)
{
alert("Incorrect Pass")
window.location="http://www/Index.htm"}
//Change the html file above
}

Thanks Shona
