Pls Help me to Create an Updatable report region

Question

hi,
can u pls help in creating an updatable report region. as of now i have 2 regions in a page. 1st region is HTML type where we can select Year,Month&Account parameters and do submit.
2nd region an updatable report region where the report generates according to the SQL query which includes conditions selected as parameters in where clause. even i have the processes to update the data in this report.
now the problem is i am able to put only one submit button which is functioning for both parameter selection and as well as updating the data in report fields. so the functionality of the report became a bit tricky which is not user friendly to the client.
whats happening is: after logging in&select the parameters month=Jan,year=2007,account=ALL
-> If you would like to update the data for Jan’07, you can enter the value in the field and click on ‘Update’ button
-> After that, if you would like to see the data for Feb’07, as of now you are not able to select the month from drop down list directly from this page and say ‘Update’. You need to log-out and log-in again and select ‘Feb’ for seeing Feb’07 data.
-> Rather if you directly select the ‘Feb’ month and say ‘Update’ in the same page, it is updating by the New value you entered for ‘Jan’ ( the same thing happens for all the months what ever you select and click on ‘Update’ in the same page without log-out and log-in)
-> So, the basic thing you have to do while you update the data is, you need to log-out & log-in for seeing or updating different month’s data after making changes to the present month and click on ‘Update’. You can not see correct data if you select the month directly after making changes to the present month’s data. This will cause automatic updating in the selected month.
sorry for the long description of my problem, but your help in this regard will be appreciated. thanks in advance.
