OT: GnuCash

[Robert Bell <robert@xxxxxxxxxxxxxxxxx>]

OK, I just don't get gnucash. I want to track a simple cash account for 
my group of Cub Scouts. I am only used to Quicken so I haven't done any 
double entry accounting before. My understanding is that I need an 
income and and an expense account? I really have two sources of income 
donations and fund raising. I created 3 accounts Donations, Fund raising 
and Expenses. Is this the correct way? So I added an entry to Donations, 
$100 for example and it tells me the transaction is not balanced. What 
does that mean, there has to be someplace I can record income without 
requiring that it come from another account right? I'm sure I'm missing 
some basic idea here.

Thanks
