Hi,
displaying the 'no values' note could also come from inappropriate filters.
I.E. if you've selected a control time as a filter ('before breakfast') without having saved at least a single bg level for this control time, you would get the message too.
If you select all values either from time frame options (2, 4, 6 weeks, ... 3 months, ... all values) and from the control times (before breakfast, ..., after lunch, ... all values) you _should_ get the values...
If not, please try the following if it's appropriate in your case: When SiDiary runs without being ever restarted, it keeps a timestamp flag for the very first day it has found a bg level. If you were adding bg levels backwards (typing some history data) it maybe still has this "first day" flag cached. But you can ensure this to be reloaded by terminating the application (not dropping it to the background). You can use the terminate button from the About/©-Tab (upper right corner) or your system task manager (settings->memory->running applications).
If you won't see any statistics after the described above, you can send me your data files (from the My Documents\ folder) and the SiDiary.ini (from the application's base folder) attached with a personal email - I'm very sure that we will get the statistics out of it!!
So long, Alf.
