Warning : The first argument should be either string or integer on contribution.

I have created the set of pricesets on contribution page. I have written the code that saves or update the drupal users account on creation of civicrm account.
When i registered myself on webform as anonymous , the drupal user is created for me. Then i went on contribution page and i selected two options for contribution and proceed with the confirm button, Then i get the transaction completed sucessfully along the ERROR:

please reply to this ques. Advance thanks to you.

I found a similar problem with my installation of 4.4.5.  On the confirmation screen for events, I was getting the same triple error message you show in your post.  Further investigation showed that something (not sure what, 'cause I couldn't get backtrace to print for some reason) is passing a 0 into the function as a double, rather than as an integer. 

I used this hack (and it is a hack) to ensure my users don't see this error message until I figure this out further.

Code: [Select]

static function value($key, $list, $default = NULL) {
  //hack to fix bug in event registration.
  if (is_double($key)) {
     $key = intval($key);
  }

   if (is_array($list)) {
      return array_key_exists($key, $list) ? $list[$key] : $default;
   }
   return $default;
}
