Please can someone help

Hi,
I'm having a bit of problem with my javascript program that i am creating. If the user inputs 1 into the dialogue box it sets up a new customer account, where the user is prompted to input their forename, surname, and a password of their own choice. when the customer has entered these details, the program allocates a customer code (first letter of first name, and first letter of last name, followed by a dash). the program should then display a welcome message, followed by the customer code, customers first name, surname and password.

Now the password should only display the first and last characters, and all other characters in between should be replaced by an asterisk. however i can not make the password do this.

please can someone help me with this problem.

thanks

Just to let you know what i'm after. when the browser displays the customers details the password should look this:

Password: C*********e

I'm not exactly sure of the syntax of Javascript but what you need to do is:
function ReturnObsficated(password)
{
var iPassLength = password.length;
var i = 0;
var ReturnString;
while(i<=iPassLength)
{
if ((i==0)||(i==iPassLength)
{
ReturnString(i)=password(i);
}
else
{
ReturnString(i)='*';
}
i = i + 1;
}
return ReturnString;
}

I think that may work but am trying to apply c++ to js, which is a recipe to disaster. Anyway try that and see if it works.

Can't right now, but I'll see if I can have a look at it later.
