[Javascript] Inherit data

[Glenn Morris]

Hello, I am new to Javascript (and this group). What I am trying to do
is as follows:
Page1.html - has 2 fields, LName and FName they are input type text.
What I am trying to do is when a person submits their name a new
document (Page2.html)
comes up with both the LName field and the FName field inherited from
Page1. The thing is I want both those fields to
be editable (input type="text") on the new form so a person could
change them. (There will be other fields on the new form but they will
not
inherit so there is no problem with them).

Some script I was working on below:

Page1.html
<Input type = "text" name="LName" ><br>
<Input type = "text" name="FName" ><br>
<SCRIPT LANGUAGE="Javascript">
var newWindow
function NextPage()
{
newWindow = window.open
("Page2.html")
}
{
newWindow.opener = self
}
</SCRIPT>
<INPUT TYPE=button VALUE="Enter" onClick="NextPage()">

Page2.html
<Input type = "text" name="LName" ><br>
<Input type = "text" name="FName" ><br>
