Survey Creator errors

I’ve been running Survey Creator (https://www.instinct.co.nz/?p=11)…

I’ve had it running on my WordPress blog for a few weeks, yet I hadn’t downloaded the results or the comments from the survey. I did that this morning and I’m getting error messages throughout the csv files that I download. no information from the survey, just error messages.

<b>Warning</b>: Invalid argument supplied for foreach() in <b>/home/.kafka/rtfldgr/blog.zimmermann2006.com/wp-content/plugins/survey_creator.php</b> on line <b>374</b>

There are three error code lines returning the same message: 362, 374 are showing up on the Survey Results download and and 420 is showing up when I download the comments.

The code in question (starting from line 361 through line 432) is here:

foreach($results as $result)
{
if($i!=0)
{
echo ",";
}
echo '"'.$questionarr[$result['questionid']].'"';
$i++;
}
echo "nr";
}
$i = 0;
foreach($results as $result)
{
if($i!=0)
{
echo ",";
}
echo '"'.$result['score'].'"';
$i++;
}
echo "nr";
//echo nl2br(print_r($questionarr,true))."";
$num++;
}
exit();
}
if(($_GET['downloadcsvcomments'] == 'true') && is_numeric($_GET['id']))
{
$id = $_GET['id'];
header('Content-Type: text/csv');
header('Content-Disposition: inline; filename="survey_comments.csv"');
$completesurveys = $wpdb->get_results("SELECT id FROM ".$table_prefix."survey-completed WHERE surveyid='”.$id.”‘”,ARRAY_A);
$questions = $wpdb->get_results(“SELECT * FROM ".$table_prefix."survey-questions WHERE surveyid='”.$id.”‘”,ARRAY_A);
foreach($questions as $question)
{
$questionarr[$question[‘id’]] = $question[‘name’];
}
$num = 0;
foreach($completesurveys as $completed)
{
$results = $wpdb->get_results(“SELECT * FROM ".$table_prefix."survey-results WHERE completedid='”.$completed[‘id’].”‘”,ARRAY_A);
if($num == 0)
{
$i = 0;
foreach($results as $result)
{
if($i!=0)
{
echo “,”;
}
echo ‘”‘.$questionarr[$result[‘questionid’]].'”‘;
$i++;
}
echo “\n\r”;
}
$i = 0;
foreach($results as $result)
{
if($i!=0)
{
echo “,”;
}
echo ‘”‘.$result[‘comment’].'”‘;
$i++;
}
echo “\n\r”;
//echo nl2br(print_r($questionarr,true)).”
“;
$num++;
}
exit();

I suck at PHP so I don’t understand what’s being presented here and what’s causing that conflict.

Any help appreciated
