Indent

Hello,
I’m a WordPress first timer and thus I have about a million questions.
One question is; in the sidebar.php I have a list that I only want to display with a certain page id. I’ve tried to look into conditional tags, but I can’t figure it out.

I have tried this in the ul tag: <?php if ( is_page(‘pageID’) ) { echo ‘1’; } ?>

Any suggestions would be most appreciated.

Best regards,
Jan
