get_post_meta selectivly working

I’m using the get_post_meta(); function as a JavaScript variable to know what page has been selected.

var page = "<?php print get_post_meta($post->ID, "Page", true); ?>";

Its working like a charm on all of my pages but one. The data just comes up blank. Consequently it is the page I have chosen to display my blog on. Not sure if this has anything to do with it.
