Broken HTML output

I’m trying to simply output a link in the middle of a post. The echoed text is displaying before everything else in the post and as a result is in the wrong place.

The code I’m trying to output is:

[php]
echo “Hello World”;
[/php]

And it shows before the divs that I have put it in.

When I swap out the Hello World for my actual goal and I visit the actual page I get:

Parse error: syntax error, unexpected $end, expecting T_VARIABLE or T_ENCAPSED_AND_WHITESPACE or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN in /home/roteva/public_html/wp-content/plugins/allow-php-in-posts-and-pages/allowphp.php(373) : eval()'d code on line 2

The link I'm building is:

[php]
"<a>loggedin_user->userdata->user_login . "/profile/edit/' class='profilelink'>P?ivit? profiilisi</a> ja saat 100xp!";
[/php]

I’ve tried escaping, [php mode=old] and a heap of other things to no avail. Anyone had a similar problem?
