Member already exists in an object module from which this object module derives

ERROR:Member already exists in an object module from which this object module derives

Bonjour,

j'ai testé cette frontière efficiente trouvé sur un ancien fil,

mais lorsque j'arrive prêt des boutons ( je ne clique pas )
je ne fais que passer prêt, et bien un msg d'erreur s'affiche à propos de la macro
Msg d'erreur:Member already exists in an object module from which this object module derives

Voici une partie du Code:

Private Function Sort(matrix() As Single, number As Long, indicator As Boolean)
'(matrix, size, min-max indicator)
'ascending as indicator = 0, decending as indicator = 1
Dim temp1 As Single, temp2 As Long
Dim i As Long, j As Long
ReDim index(number) As Long
For i = 1 To number
index(i) = i
Next i
For i = 2 To number
temp1 = matrix(i)
temp2 = index(i)
For j = i - 1 To 1 Step -1
If indicator = 0 Then
If matrix(j) <= temp1 Then
Exit For
End If
Else
If matrix(j) >= temp1 Then
Exit For
End If
End If
matrix(j + 1) = matrix(j)
index(j + 1) = index(j)
Next j
matrix(j + 1) = temp1
index(j + 1) = temp2
Next i
Sort = index(1)
End Function

Merci
