Try this instead of the SendRaw line:
<font class="small">Code:</font><hr /><pre>
ControlSend, SysListView321, % table_name%array_count%, ahk_id%lobby_id%
</pre><hr />
That's the way I've done it in the past. It
may not work with the array reference in the call, sometimes AHK is like this. If so, try:
<font class="small">Code:</font><hr /><pre>
tn := table_name%array_count%
ControlSend, SysListView321, %tn%, ahk_id%lobby_id%
</pre><hr />
instead.
Good luck,
