query in reading data from the backend

[srivalli]

in my form i have the following fields:

issuedate id issuedamt returnedamt dischargeddate and values r:

15.4.99 11/05 40000 0 14.9.2005


i entered the above fields along with some other fields (say address etc)

here my query is:
when i give dischargeddate in issued data and when i mention the same id , i want to retieve all the fields and the amt which i mentioned in issuedamt should shift to returnedamt and whatever fields i entered in addition to these fields should displayed .

that is:

issuedate id issuedamt returnedamt dischargeddate
14.9.2005 11/05 0 40000 -
