Put the following code in the sheet module for the worksheet that
contains the cell with the validation:

Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
If Target.Address = "$A$1" Then
Worksheets(Target.Value).Select
If Err.Number < 0 Then
Worksheets.Add.Name = Target.Value
End If
End If
On Error GoTo 0
End Sub


Change $A$1 to the cell with the validation list.

...
i have a workbook with a sheet in wich a cell, with data
validation, can
display a serie of names; i.e., example1, example2, example3,
.....

what i want is this:

if i select in that cell, for example, example1, then if sheet
example1
exists it will be slected, otherwise it will be created with
that name.

is this clear? i hope so :)

i´ll apreciate any solution, and ..., thanks in advance.
