I am trying to replace Appenidix # with Table #.#  Only difference is I
cannot replace all Appendix # with Table #.#. I mean how will I use fields to
replace numbers(#.#) using find and replace command. My files can be of
5-50page it depends.

Any help.. it's very urgent

I am using following macro to do this.

Selection.Find.ClearFormatting
   With Selection.Find
       .Text = "Appendix 1"
       .Replacement.Text = "Table "
       .Forward = True
       .Wrap = wdFindContinue
       .Format = False
       .MatchCase = False
       .MatchWholeWord = False
       .MatchWildcards = False
       .MatchSoundsLike = False
       .MatchAllWordForms = False
       Selection.Fields.Add Range:=Selection.Range, Type:=wdFieldEmpty,
Text:= _
       "SEQ Table\c ", PreserveFormatting:=True
   Selection.TypeText Text:="."
   Selection.Fields.Add Range:=Selection.Range, Type:=wdFieldEmpty, Text:= _
       "SEQ Table\c ", PreserveFormatting:=True
   End With
