Both gtk_notebook_get_current_page and gtk_notebook_get_nth_page
work fine with me. I suspect that your problems might come from
the "switch_page" signal, which is a bit tricky: gtk_signal_connect 
might not be the right choice. Did you connect this signal to some 
callback? Can you give more details?

This is a stripped example for the switch_page signal callback:
---------------------------------------------------
static void static_switch (GtkNotebook *notebook, GtkNotebookPage *page, guint tag, gpointer data)
{
GtkWidget* vbox = gtk_notebook_get_nth_page (GTK_NOTEBOOK (notebook), tag);
GtkWidget *entry;

entry = gtk_object_get_data (GTK_OBJECT (vbox), "value");
gtk_entry_set_text (GTK_ENTRY (entry), "");

switch (tag)
  {
  case 2:
  entry = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (vbox), "name4");
  gtk_entry_set_text (GTK_ENTRY (entry), "");

  case 1:
  entry = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (vbox), "name3");
  gtk_entry_set_text (GTK_ENTRY (entry), "");

  case 0:
  entry = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (vbox), "name2");
  gtk_entry_set_text (GTK_ENTRY (entry), "");
  entry = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (vbox), "name1");
  gtk_entry_set_text (GTK_ENTRY (entry), "");
  break;
  }
}

This is another stripped example for a reset function:
-------------------------------------------------------
static void static_reset (GtkWidget *dialog)
{
GtkWidget *notebook = GTK_BIN (dialog)->child;
gint page = gtk_notebook_get_current_page (GTK_NOTEBOOK (notebook));
GtkWidget* vbox = gtk_notebook_get_nth_page (GTK_NOTEBOOK (notebook), page);
GtkEntry *entry;

switch (page)
  {
  case 2:
  entry = (GtkEntry *) gtk_object_get_data (GTK_OBJECT (vbox), "name4");
  gtk_entry_set_text (entry, "");

  case 1:
  entry = (GtkEntry *) gtk_object_get_data (GTK_OBJECT (vbox), "name3");
  gtk_entry_set_text (entry, "");

  case 0:
  entry = (GtkEntry *) gtk_object_get_data (GTK_OBJECT (vbox), "name2");
  gtk_entry_set_text (entry, "");
  entry = (GtkEntry *) gtk_object_get_data (GTK_OBJECT (vbox), "name1");
  gtk_entry_set_text (entry, "");
  }
}
