Are you trying to get this:

Dim c as String
Dim n as String
Dim Cojonudo as String

Public sub fff
c="Cojo"
n="nudo"

Cojonudo  = c & n

HTH,

Hi every one,

basically I need to solve this problem:

Dim c as String
Dim n as String
Dim Cojonudo as String

Public sub fff
c="Cojo"
n="nudo"

c & n = "whatever"

end sub

But this doesn´t work, any idea how can I create the variable based in
the other two.

Thanks

I don't think I understand exactly what you are trying to do:

Public Sub fff()
Dim c As String
Dim n As String
Dim Cojonudo As String
c = "Cojo"
n = "nudo"
Cojonudo = c & n
MsgBox Cojonudo
End Sub
