If you complete the questionnaire on-line and try to submit it and you get a message that the file cannot be found or the address is invalid, you're probably either accessing an obsolete version of the instrument or your pop-up blocker is keeping the instrument from functioning properly.
To get to the right version, go to the web-based version of the instrument, complete and submit it. A form showing your learning style profile should be returned immediately. If you know you are accessing the most recent version of the instrument, try turning off your pop-up blocker and completing and submitting the form once more. The only other possibility is that the server on which the ILS resides is having a temporary problem. Let some time pass, and try again.
