Assistance with Combining Scripts

[Charger27]

Hi all
I have used many scripts from DD over the years, so now when I am stumped - I figured here was the place to turn for answers.
I've looked around the topics for a solution, but haven't been able to find a relevant one.
I design web sites as a hobby and comprehend graphics, etc - but scripting doesn't have to be very complicated before it's over my head.

Here is what I've got:
1. I found a basic javascript login on the net... it works fine.
Yes, I know how insecure this type of login is - but it is adequate for what I am doing.

2. On the destination page, I have a simple document.referrer script to prevent direct url entry... it works fine.

3a. In Firefox, this setup executes without an issue - but in Internet Explorer the http referrer header returns empty, thus activating the document.referrer.

3b. I have an Internet Explorer update script to fix the problem in 3a... it tests fine.

Problem:
I cannot figure out how to combine the IE update and the main script, because I don't understand html well enough.

The main login script:

<script language="javascript">
<!--//
/*This Script allows people to enter by using a form that asks for a
UserID and Password*/
function pasuser(form) {
if (form.id.value=="my_username") {
if (form.pass.value=="my_password") {
location="points_to_the_workaround_script"
} else {
alert("Invalid Password")
}
} else { alert("Invalid UserID")
}
}
//-->
</script>

<center>
<table bgcolor="white" cellpadding="12" border="1">
<tr><td colspan="2"><center><h1><i><b>Login
Area</b></i></h1></center></td></tr>
<tr><td><h1><i><b>UserID:</b></i></h1></td><td><form name="login"><input
name="id" type="text"></td></tr>
<tr><td><h1><i><b>Password:</b></i></h1></td><td><input name="pass"
type="password"></td></tr>
<tr><td><center><input type="button" value="Login"
onClick="pasuser(this.form)"></center></td><td><center><br><input
type="Reset"></form></td></tr></table></center>


The necessary Internet Explorer update script:

<a href="the_destination_page"
onleftclick="window.open('','newwin','height=1000,width=1024','')"
target="newwin"></a>

Any help would be greatly appreciated.
Thanks in advance.

A programmer friend of mine expressed some confusion as to what I am asking - perhaps that is why I am getting no responses here either.
The frustrating part is I don't know the language to properly ask the question... so I will draw a colored layout which will hopefully make things more clear.

Black = the main script
Green = the supplemental script
Red = the desired action


<script language="javascript">
<!--//
/*This Script allows people to enter by using a form that asks for a
UserID and Password*/
function pasuser(form) {
if (form.id.value=="my_username") {
if (form.pass.value=="my_password") {
location="points to the green anchor script"
} else {
alert("Invalid Password")
}
} else { alert("Invalid UserID")
}
}
//-->
</script>

<a href="the_destination_page"
onleftclick="window.open('','newwin','height=1000,width=1024','')"
target="newwin"></a>

<center>
<table bgcolor="white" cellpadding="12" border="1">
<tr><td colspan="2"><center><h1><i><b>Login
Area</b></i></h1></center></td></tr>
<tr><td><h1><i><b>UserID:</b></i></h1></td><td><form name="login"><input
name="id" type="text"></td></tr>
<tr><td><h1><i><b>Password:</b></i></h1></td><td><input name="pass"
type="password"></td></tr>
<tr><td><center><input type="button" value="Login"
onClick="pasuser(this.form)"></center></td><td><center><br><input
type="Reset"></form></td></tr></table></center>


Maybe this visual will make for an easier understanding of what I am trying to accomplish.
I simply need some code to connect the location= to the <a href> which is neccessary for this login script to work with a document.referrer in Internet Explorer.
