My A/R transactions are not getting posted to the client account.

SOLVED

Hi, I am having an issue that I never had before.  Using Timeslips 2013.  In my A/R transactions I see the client file showing all invoices and payments and a $0.00 baklance due.  When I generate my new bill for the quarter the invoice shows the amount due for this cycle and then a total balance due which is different as it is adding the unposted balance from a previously paid invoice to the new invoice.  Further ionvestigation shows that the items previously paid are listed in the A/R Transactions, however, they are not Posting as paid.   There is nothing due, all previous invoices have been paid in full, but some have not posted as paid to the account.  Some are write offs and some are actual payments.  Can anyone tell me how do I get my system to post payments again?   Thanks....
