Online/Offline text problem

[Challenge]

Hi friends.
I've added 3 new Phrases -

Type: GLOBAL. Title: x_is_offline2. Text: Ofline.

Type: GLOBAL. Title: x_is_online_now2. Text: Online.

Type: GLOBAL. Title: x_is_invisible2. Text: Ofline.

Then ive added this to my postbit template:

<if condition="$onlinestatus==0"><phrase 1="$user[username]">$vbphrase[x_is_offline2]</phrase></if>
<if condition="$onlinestatus==1"><phrase 1="$user[username]">$vbphrase[x_is_online_now2]</phrase></if>
<if condition="$onlinestatus==2"><phrase 1="$user[username]">$vbphrase[x_is_invisible2]</phrase></if>

But when i see a thread, whatever if i'm Online or Offline it always say "Ofline".
Why is that?
Does anyone have a better idea to how i can do a Online Offline text in my postbit? (Not by replacing the online/offline image.)

Regards,

Challenge.

Somebody knows?
