Transfering data to another page

[claws2rip]

Hi.........


I have 3 webforms (page1, page2 and page3)

On page1 there is a button that opens page2. At is time i page1 and page2 open. On page2 there is a button that opens page3. At this time i have page1 and page3 open.

now here is my problem.............
From page3 I would like to pass a value to page1 (which is still open).
When I attempt to do this it opens up a second page1.

Any suggestions??
If it's not clear please let me know.....
