This & is the concatenation operator...basically it just combines your variables...so you can do this
if your working with multiple pages..use session variables
Code:
fName = Session("fName") 'on page 1
mName = Session("mName") 'on page 2
lName = Session("lName") 'on page 3
Full Name = Session("fName") & " " & Session("mName") & " " & Session("lName")
so if Session("fName") = "George"
and Session("mName") = "Walker"
and Session("lName") = "Bush"
Full Name will look like this "George Walker Bush"
