End Sub

Private Sub cmdAdd_Click()
Dim lastrow
lastrow = Sheet1.Cells(Rows.count, 1).End(xlUp).Row
lastrow = lastrow + 1
Cells(lastrow, 1) = TextBox1
If Application.WorksheetFunction.CountIf(Range(“A2:A” & lastrow), Cells(lastrow, 1)) > 1 Then
MsgBox “Duplicate data”, vbCritical, “Remove Data”
Cells(lastrow, 1) = “”
ElseIf Application.WorksheetFunction.CountIf(Range(“A2:A” & lastrow), Cells(lastrow, 1)) = 1 Then
answer = MsgBox(“Are you sure you want to add the record?”, vbYesNo + vbQuestion, “Add Record”)
If answer = vbYes Then
Cells(lastrow, 1) = TextBox1.Text
Cells(lastrow, 2) = TextBox2.Text
Cells(lastrow, 3) = TextBox3.Value
End If
End If

End Sub
