Statements in QuickBooks

I have just started using QuickBooks to prepare monthly statements for a condominium association. Each statement includes an assessment fee, cable television fee, utilities fee, and parking fee. Only the utility fees change monthly. I wanted to make December's statement as simple as November's, but when I tried to update the November statements to reflect December charges, the November payments show up as credits for December. How can I get the December statements to exclude the payment for November? I've tried changing dates in the statement printing window but to no avail. And the memorized transactions for November will not automatically work.
