how do i now allocate payments for the client to show on the client's statement when payments were made

thanks again, much appreciated

i changed the client's payment terms to 30 days - no problems
created a new invoice - no problems
checked statement - no problems
now when i go " Reports and Analysis / Print Invoices  " the system simply does not show anything. no error

when i try to allocate a payment it still will not allow me to do so

any ideas, please i urgently require the system to make payments as i need to send out statements asap

one more thing. i noticed that in my " Fiscal Years " i have three years being:
Fiscal Year Begin     Fiscal Year End     Closed        
01/03/2009                       28/02/2010           No
01/03/2010                       28/02/2011               No
01/03/2011                       29/02/2012               No

when i try to close to top two the system simply does nothing

installed and using fa 2.35

when i try to allocate a payment it does not seem to update as the screen does not refresh saying that the payment has been made.

when i check the client's statement the payment does not reflect

any ideas what i need to do?

thanks again for a great product
