What we are missing is how you got 'name' to the second page. Whatever
variables you create in one page are completely destroyed when a new
page loads, even though you are creating them as globals.

function prompter(button)

What calls the function? Does it return anything? Does some other
function do something with the global variables you create?

{

name=prompt('What\'s your name?',"Please enter your name here");

Why is 'name' created as a global variable?

Response=alert("Welcome "+name);

'Response' is assigned a value equal to whatever is returned from
alert(...), which is nothing, so 'Response' is undefined. What is the
point? If you want to show what was entered to the prompt, then:

alert("Welcome "+name);

does the job.

both = name.split(' ');

This will create a global variable called 'both' that is an array of the
split parts of name.

firstname = both[0];
lastname = both[1];

Now you have two more global variables. If no spaces were entered,
'lastname' will be undefined. If nothing at all is entered, firstname
will be '' and lastname will be undefined. If ' blah' is entered,
firstname and lastname will be ''.

What are you trying to do?

Rob,

I have put the whole code of the first page below - I can then use the
value of the name variable on the second page using IE v6. Now how is
that possible?!

'name' is effectively a reserved word as the variable window.name is created automatically, but is not read-only.
Use more imaginative names for variables.

Stephen,

Regret have only just had my attention drawn to your reply. I am not
seeing it using Agent for some reason.

Are you saying that I can use the "name" (variable) value in the second
page because of window.name ?
