Good evening!
Now, if I can't edit excel-files - is there any other way I can keep track of my pupils presence and efforts?!
I've always used excel for this purpose before. But now I became so aroused with the P800 so I just had to buy it...
Please, point me in the right direction ....

Try this - its a spreadsheet midlet application. Maybe a stand in till something better appears:

Thank you, Rafe!
I'll soon see if it works ...
Happy New Year!
