Highlight Nav Not Working Conditional

Hi I have a page called home.php (index) which calls on header.php..

I have this for my main nav but it isnt converting my nav item to be highlighted like other nav items..

Below is statement

<li id=”topnav-1″>
<?php if (is_home()) { echo ‘ class=”current”‘; } ?>”>Home

These other nav items work just fine:

<li id=”topnav-2″>/services” <?php if ( is_page(‘services’) ) { echo ‘ class=”current”‘; } ?>>Services

Help appreciated!
