I get the following error message in running Two samples t-tests Practice in moodle (using Chrome, also similar , less verbose message in IE). However, it runs OK in numbas-editor.

TypeError: Cannot call method 'selectSingleNode' of undefined at Numbas.xml.tryGetAttribute (https://moodle.mas.ncl.ac.uk/pluginfile.php/1038/mod_scorm/content/4/scripts/xml.js:111:19) at Object.Numbas.Question (https://moodle.mas.ncl.ac.uk/pluginfile.php/1038/mod_scorm/content/4/scripts/question.js:38:2) at Object.

Resolved! This is because I had been running an earlier version which subsequently had two questions removed, and it was trying to resume this. After clearing all attempts, the exam worked.
