User's Ranks Help

[Tasking Mickey]

I put the

PHP Code:

<vb:if condition="$post[fieldx'] != 'No'"> 


In front of the rank code, in the postbit, and put the

PHP Code:

</vb:if> 


at the end of the rank code,

And this is the rank code,

PHP Code:

<if condition="$post['rank']"><div class="smallfont">$post[rank]</div></if> 


And when I clicked save, said there was an error in the template, please go back and fix it.

BTW: On 3.8.6 vbulletin.

Am I putting in the wrong way?
