Icash conditional help

Ok I?ve connected Icash with ibProArcade and it work great. But I have a question. Can I let the guests play at the arcade? Because when they play it says ?you don?t have enough
money?

The plugin looks like this.

PHP Code:

$amount = '1';

if (($vbulletin->userinfo[$vbulletin->options['icashf']] - $amount) < 0) {
          eval(standard_error(fetch_error('error_cash_arcade')));
}
$vbulletin->db->query("update " . TABLE_PREFIX . "user set {$vbulletin->options['icashf']}={$vbulletin->options['icashf']}-'{$amount}' where userid='{$vbulletin->userinfo['userid']}'"); 

Can you suggest me a conditional too ignore this plugin if ?guest? ?

Thanks

check the arcade permission value, if this is >2 it is a guest playing...
or just check for userid, if this is zero it surely is a guest - but remember that you can enable guests to save scores in the arcade and then they use a unique userid (setup via arcade-settings)

Thanks for the reply MrZeropage. I know how to find a userid but I don’t know what code use in that plugin so it don’t charge the amount ‘1’ or check for icash amount for guests.

Any ideas?
