Allday Consulting's Peachtree and QuickBooks Support Boards

I am new to Peachtree and the employee whose job I took is being no help at all! I am trying to reconcile the September (Period 21) statement. My accounting period was still listed as August 2009 (Period 20). I went to change the accounting period to the Sept. period, and it checks for unposted entries. Well, then I get this warning message "Period changed to 22 due to unposted journal entries there". Period 22 would be October of this year. The posting method we use is real-time so things are automatically supposed to be posting, right? What am I missing here? I started this job in April of this year and this is the first time this has happened to me when reconciling the account. Any help would be greatly appreciated!!
Thanks!!!
