Hi Doc60,
If you use a formula field for the calculation, then something as simple as doing a print preview will be enough to get it to
recalculate. Alternatively you could use a macrobutton field to drive a simple macro, coded like:
Sub ReCalc()
On Error Resume Next
ActiveDocument.Tables(1).Range.Fields.Update
End Sub
For some pointers on the use of formula fields, check out my Word Field Maths 'tutorial', at:
