I did not use the import template option, changed new template name to Budget New.

This same file was used last year, the only thing I changed was the numbers, and to add any new accounts, I carefully copied the row before changing. The budget showing for the current month (period 3) is exactly the budget numbers for (period 1) and if I change the date to March there is zero for the budget numbers.

Should I give up and add all the budget numbers by hand?

There should be instructions if the procedure has changed from Version 8.1 to Version 9.
