[VB4] Need help with variables

[HolySell]

Hey vBulletin.org-Community

I have a problem with my variables

I want to "echo" a variable called "gfxpoints"(numeric) in my template "memberinfo_block_ministats", the variable "gfxpoints" should read out with a mysql_query from table user, my question, where I must register the variable gfxpoints that this code in the "memberinfo_block_ministats" works ?

<dl class="stats">
<dt>GFX-Points</dt>
<dd>{vb:raw gfxpoints}</dd>
</dl>

i have tried to register the variable "gfxpoints" in the member.php but it won?t work
