Excel Responses File - Failure

[petrocjv]

I'm using MediaLab 2006 and Windows Vista. I've programmed a responses file to feedback some score calsulated in Excel. I had it working yesterday, but today it doesn't work. I've got a fill in the blank event labeled "est1" and in Excel I have "est1" and then "f1" and "a1" - both of which get caluclated in Excel. Then on the next event in MediaLab I feedback the scores using "<f1>" and "<a1>". If data is entered into the fill in the blank event, the feedback screen displays for 7 seconds (as I've programmed it) but nothing is displayed (not the content nor the f1 and a1 values). Its very strange. Also, if I press Ctrl + -> (right arrow) during the "est1" fill in the blank event, the feedback frame content is displayed, but with values calculated as if 0 was entered into the fill in the blank event. So, if no response is given you get feedback, but if a respons is given you don't get any feedback - what gives? Has anyone had problems with this kind of thing? I'm beginning to think its not a Vista problem as the same occurs on an Windows XP computer. Also, I've kept the Excel file as a 2003-2007 file with the "xls" extension rather than the "xlsx" extension. John Petrocelli
