Invalid argument supplied for Write-ins option!

First of all, thanks ChrisKennedy very much for porting this module.

This bug may be related to this issue (http://drupal.org/node/345059) in somehow, if it is duplicated issue sorry for that.

When I select a "Allow users to cast a write-in vote" for the poll, I got this error when I hit Write-in option:

warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\6\sites\all\modules\advpoll\advpoll.module on line 1723. 
warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\6\sites\all\modules\advpoll\advpoll.module on line 1630. 

Also, when I press "Promote", I got this error:

warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\6\sites\all\modules\advpoll\advpoll.module on line 1723.

Other things, so far work with me perfectly, thanks ChrisKennedy!
