Executing NavigationCommands.Zoom

Hi there:

I'm trying to execute NavigationCommands.Zoom from a Context Menu, but I don't know what to put in the second parameter:

NavigationCommands.Zoom.Execute(e.Parameter, ??);

My code is this:

<FlowDocumentPageViewer Name="flowDocumentPageViewer" MinZoom="50" MaxZoom="200"><FlowDocumentPageViewer.ContextMenu><ContextMenu><ContextMenu.CommandBindings><CommandBinding
                        Command="NavigationCommands.Zoom"
                        CanExecute="navigationCommandZoom_CanExecute"
                        Executed="navigationCommandZoom_Executed" /></ContextMenu.CommandBindings><MenuItem Header="50%" Command="NavigationCommands.Zoom" CommandParameter="50" /><MenuItem Header="100%" Command="NavigationCommands.Zoom" CommandParameter="100" /><MenuItem Header="150%" Command="NavigationCommands.Zoom" CommandParameter="150" /><MenuItem Header="200%" Command="NavigationCommands.Zoom" CommandParameter="200" /></ContextMenu></FlowDocumentPageViewer.ContextMenu><FlowDocument><Paragraph>

Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae;</Paragraph></FlowDocument></FlowDocumentPageViewer>

private void navigationCommandZoom_CanExecute(object sender, CanExecuteRoutedEventArgs e) {
    e.CanExecute = true;
}

private void navigationCommandZoom_Executed(object sender, ExecutedRoutedEventArgs e) {
    NavigationCommands.Zoom.Execute(e.Parameter, ??);
}

Any suggestion?
