[Can't access state.variable in clif function]

Hi all.

I'm writing a small atcommand which changes the view of the party window.

The atcommand reads and writes fine from sd->state.partyview, in clif.c I can access sd->state.partyview inside clif_party_info, howerver, it crashes my mapserver everytime it sends the info to the client.

Just this way:

if(!sd->state.partyview)
{
 memcpy(WBUFP(buf,28+c*46+4), m->name, NAME_LENGTH);
}

It's just the argument in the conditional that crashes my server. Is there any workaround? I just want a variable for every char which I can change through an atcommand.

Thank you.
