Profile Field not working

[Greenskull]

Hey. I'm trying to call a profile field in MEMBERINFO but it doesn't regocnize it or any other profile field. What is wrong? Here's what the code is:

<if condition="$post[field5]">
<img src="http://avatar.xboxlive.com/avatar/$post[field5]/avatar-body.png"></img>
</if>
