I have been developing in Lectora for a year, but due to our limitations, have been publishing the courses as exe. We now have a Web site where we can publish the html versions of the courses. We just came across this problem on fill-in-the-blank questions.If a 0 (zero) is entered, the course freezes and I get a Java script error symbol at the bottom of the screen. The error is "Object doesn't support this property or method."Any other single digit alpha/numeric character simply gives me the message that my answer is wrong.Can anyone shed some light on this?Thank,Linda
