VB:IF quesiton concerning usergroupID

[ed762]

The users in my board are all in the primary group of registered member, and some are additional users of other groups.

I want to display certain graphic in the postbit for the members in the primary registered user usergroup, who are also additional members of the usergroup 10,11,12.

For example, a user will be a primary user of group 2 ( registered users) and an additional user of group 10 ( or 11 or 12)

So I put the following into the postbit template:

<vb:if condition="in_array ($post[usergroupid], array(10,11,12))">

XXXX

</vb:if>

But that does not work. Does the statement not work on group ID of an additional user?
