Vbphrases - how do i register from template instead of php

[Vaupell]

EDIT : read last post first please..

*** original post ***
got some old phrases

like this

$vbphrase[Euclength] and when i use that it places the lang value for me in english which i have as "length"

so now i want to make it work for vb4, cause atm it just shows the actual phrasecode.
so i change it from

$vbphrase[Euclength]

to

{vb:raw vbphrase.Euclength}

but now it comes up empty as if it dosent retrive the data..
any ideas what im doing wrong ?
cause ive changed a few others they came out just fine.. so im guessing my syntax is fine.
