[Plugin: WP Survey And Quiz Tool] Likert questions error

I am getting the following error when I add a Likert question to a survey and then try and fill the survey in:

Warning: current() [function.current]: Passed variable is not an array or object in /home/janetbru/public_html/b-active/wp-content/plugins/wp-survey-and-quiz-tool/lib/Wpsqt/Shortcode.php on line 539

If I try and look at the results I see this for the Likert question:

array(3) { ["name"]=> string(35) "How would you rate your experience?" ["type"]=> string(6) "Likert" ["answers"]=> array(10) { [0]=> array(1) { ["count"]=> int(2) } [1]=> array(1) { ["count"]=> int(0) } [2]=> array(1) { ["count"]=> int(0) } [3]=> array(1) { ["count"]=> int(0) } [4]=> array(1) { ["count"]=> int(0) } [5]=> array(1) { ["count"]=> int(0) } [6]=> array(1) { ["count"]=> int(0) } [7]=> array(1) { ["count"]=> int(0) } [8]=> array(1) { ["count"]=> int(0) } [9]=> array(1) { ["count"]=> int(0) } } }

Any idea what is going on? I’d really like to use Likert on my survey.
