My guess would be in line with yours, that he clicked the radio button but did not hit the submit button for that part. When he submitted the third question, Lon-Capa knew about the radio button but did not evaluate it. It didn’t show up with the question 4 submission because when the page reloaded after question 3 was submitted, question 2 went back to its default of no selections, since it had not been submitted, evaluated, etc. That’s what I expect took place, but am eager to learn if that is not correct.

This happened during a quiz so he didn't get the problem status, or a receipt, at the time of the submission. In looking through the activity file I see something that I don't understand and was wondering if it was somehow related. The problem has 4 parts. The 2nd part is a radiobuttonresponse and it is the one that the student claims to have answered. In the activity log excerpt below, the 2nd part is HWVAL_14. The thing that I don't understand is that HWVAL_14 doesn't show up in the POST on line 469 for the 1st part like the other parts do. Then it shows up on line 468 with a value. Line 468 is a POST for the 3rd part as indicated by the submission in the CSTORE on line 467. Then on line 465, the POST for the 4th part, HWVAL_14 is missing again. Looking at the issue of not getting credit for the submission, did he click on a radio button but not the submit button for that part (the 2nd part). Then when he submitted his answer for the 3rd part, the 2nd part POST'ed too but lon-capa didn't grade it since the submit was not for the 3rd part. That seems reasonable. Is there an explanation for the line HWVAL_14 appearing and disappearing? I thought maybe the activity log might be corrupt but grading indicates "Nothing submitted - no attempts." Are these 2 things related?
