Hi Sonia,

Did you add the items after some initial test runs? And are you looking at the SPSS .sav data file? If so, remember that the .sav file can not have variables added to it after it has been created. So if you add items, try clearing out your data folder and then run a test session. If this is the problem, you should now find that everything is writing OK. This same problem creates trouble for .csv and .txt dat files but only in so far as the data won't match the origional file headers.

Bottom line is that if you've made some changes to your experiment structure, try clearing your data folder and doing a fresh run. If that doesn't fix it, please let me know.
