Thanks for your reply.
I have managed to get the data to copy across to the new form but can't have explained myself very well.
The problem that I had was that the form not only contained an address, but also name and date of birth.
I only want to copy the address portion of the form accross.
I have tried to find the code which selects the form elements to retrieve the data but I haven't managed to do this - I was hoping to be able to delete the references to the name and dob form fields.
Would you suggest naming these fields differently on the second form so that the data isn't populated?
