[Plugin: WP Survey And Quiz Tool] Survey Total Results does not display proper count

when displaying survey total results i get an error message at the bottom of the chart

—
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wordpress\wp-content\plugins\wp-survey-and-quiz-tool\pages\admin\surveys\result.total.php on line XX

i managed to fix this by changing $surveyArray(‘scale’) to $surveyArray(‘multiple’)

but this does not solve the Average and Total Votes count. it simply displays a zero count on both fields.
