Question on reports

[Bob Alexander]

Dear Friends,
it has been a while now that I am happily using Gnucash to ENTER my 
expenses and other financial data.

A few weeks ago my wife asked me to understand how much we have spent on 
our summer vacation.

I tried with the reports but could not quite obtain what I needed.

Here follows a description of what I'd like to achieve.

Thank you for any help.
Bob

Vacations go from date X (5 Aug 2005) to date Y (25 Aug 2005).
In this timeframe I would like a figure of how much I spent.
Spending includes the credit cards and the ATM (I can ignore some cash I 
had in the beginnings).
ATM shows up as withdrawals from my banking account.
Credit cards have their own Liabilities account.
What I spent through the credit card also shows up in the expense 
category and it's subcategories.
Bars, pies etc. are not that interesting. I'd like to have numbers.
