You could use a macro to retrieve a value right before you print/print preview.

This goes behind the ThisWorkbook module:

Option Explicit
Private Sub Workbook_BeforePrint(Cancel As Boolean)
With Worksheets("sheet1").PageSetup
.LeftHeader = "a little stuff"
.CenterHeader = "what you want here"
.RightHeader = .range("a99").text
End With
End Sub

Hi, Is it possible to set up a Header in which I can have something like a
"Field" that get's its data from some part of the worksheet, maybe with some
sort of Lookup or something?
