adding a custom field to a link

Not the best at php but i think those that are will see what I’m trying to do. I have a custom post type that that i want to add a link to at the end and thought i’d use a custom field that i’d enter something like, “projects” to and in the code i was thinking of having the blog url link + “projects” if there is a better way, please feel free.
this is what i thought would work:

<?php if ( get_post_meta($post->ID, "Category Link", true) ) { ?>
<a href="<?php bloginfo('template_url') . get_post_meta($post->ID, "Category Link", $single = true); ?>" ></a>

				<?php } ?>
