Scores disappearing

Hello All, I am using Lectora 2006 SP5. I have constructed a quiz with multiple evaluations and chapters. There is a main page which branches out a number of sub pages with multiple quiz sections. I have variables that return the number of questions a delegate has attempted and how many they got correct. If a quiz has not been attempted then it displays 'not taken'. I have completed about half the quiz in the Accenture LMS and have all scores displaying correctly. I can close the quiz, logoff and back on and the scores are retained. If I leave it a day or so, then go back in some sections that I have previously completed are now showing as 'not taken'. It is as if a variable has reset back to zero - I have checked that variables are ticked as being retained between sessions and anyway would have expected that to happen immediately I log off and on again if that was the problem.Has anyone else seen this problem before and can give me a hint where to look.Thanks in advance, Iain...
