[OciXCrom]

I really don't understand why it is so difficult for you to copy/paste a single line of code. Where did you see me mention anything about creating a format inside the .sma file? That's not how the function works. It requires a format identifier, not the entire format line inside it.

#include <amxmodx>
#include <chatmanager>

public plugin_init()
{
    register_plugin("CM: Setinfo Prefix", "1.0", "OciXCrom")
}

public client_putinserver(id)
{
    cm_on_player_data_updated(id)
}

public cm_on_player_data_updated(id)
{
    new szInfo[2]
    get_user_info(id, "vip", szInfo, charsmax(szInfo))

    if(str_to_num(szInfo) == 1)
    {
        cm_set_user_say_format(id, "format_admin", "format_admin_team")
        cm_set_user_prefix(id, "[YOUR PREFIX HERE]")
    }
}

Tested and working.
