how i make hock to run in one style

[shqawe]

hey all,

i'm making product and one from my options is:
select style to run the product with it.

and i put this code for this option:

PHP Code:

select:eval
$options = fetch_style_title_options_array(); 


now in my plugin area i write this code:

PHP Code:

if ($vbulletin->options['act'])
{
  if (in_array($foruminfo['styleid'],$vbulletin->options['style'] ))  {
 eval('$change_th_rp = "' . fetch_template('change_th_rp') . '";');
$vbulletin->templatecache['forumhome_forumbit_level2_post'] = $vbulletin->templatecache['change_th_rp'];    
}
} 


when i run my product i got this error:

PHP Code:


Warning: in_array() [function.in-array]: Wrong datatype for second argument in C:\AppServ\www\vb\index.php(67) : eval()'d code on line 5 


can any one help in my problem.

Thanks in advance.
