Thanks Chelli:

I appreciate the work you have put into gnumeric.

The app seems to work fine.

For people looking for a bit more than a simple budget spreadsheet this one seems to work fine.

I originally set it up on the laptop then transfered to n800.

Note: To get to the monthly sheets on the n800 go to
Format --> Sheet --> Manage Sheets and double click on the sheet you would like to access. I am sure there is an easier way, but it is eluding me.

Enjoy and thanks
