Estimating budget not working

[Peter Barnshaw]

Hi,

I am a long-time user of GnuCash and have a question regarding budgeting. I
am on GnuCash 2.6.17.

When I try estimate the budget, it comes up with 0 as the budget number
despite there being over 18 months of data in my accounts. Why is this the
case and can I get the estimate to work rather than manually having to type
in the previous year's spend in a particular month.

Many thanks in advance,

Peter
