Simple PHP code in Text Widget

I am trying to put the following in a Text widget…

<?php
if ( is_front_page() == 1 )
{
echo “Text for frontpage.”;
}
else
{
echo “Block of text for all other pages.”;
}
?>

… the thing is it works perfectly, when I’m logged in but displays nothing at all to any logged out visitors!?

Any help please?

Thank you very much.
