I'd like to add a donation page to the website. But I can't figure out how to add the link to it on the member's menu. I have created the donation.php page, and put it in the engine/forms folder. I have opened the members_menu.html which located in the templates folder, and added the following:

<a href="index.php?page=account" class="bob">{LANG[HTML][MEMBERS_MENU][7]}</a> | <a href="index.php?page=donation" class="bob">{LANG[HTML][MEMBERS_MENU][17]}</a>

When I view the member's menu online, the donation link is not there. Could someone please tell me how to get this to work? I'm sure it has to do with the numbers, 7 and 17, as I'm not sure what to do with them, or why they are needed.
