Complicated Code HELP!

Question

<br><br>
Hi Below is my code that works out the start date - the end date * the lpa_amount divided by 7,
If the is more than one ent_seqno it will do the same for the 2nd, 3rd etc ent_seqno and total them up.
claim_no     Ent_seqno    Start_date    End_date        lpa_amt
1000052847     1     01/04/2008     18/05/2008     0.762     
1000052847     2     19/05/2008     31/03/2009     0.71     But my problem is if i try to choose the start and end dates, i thought simply by inputing
SUM ((:p_end_date - :p_start_date +1 )
instead of
SUM ((lpa_history.p_end_date - lpa_history.START_DATE +1)
It would work but it doesnt, it only works out calculations for just the first ent_seqno and ignors any others.
Please Please help!!!

Hello, sorry people it is quite, complicated and i will try to explain in more dept!!!
claim_no     Ent_seqno    Start_date    End_date        lpa_amt
1000052847     1     01/04/2008     18/05/2008     0.762     
1000052847     2     19/05/2008     31/03/2009     0.71
[pre]
Basicly my code picks up claims, that are PTEN, HA, and ELIGIBLE, from the CLAIM table,
once it has a claim, it then has to work out they payment from the history table,
an example of a claim from the history show above.
it subtracts the start date from the end date +1 and multiplies it by the amount and then divides by 7,
so the answer for the above would be:
01/04 - 18/05  +1 = 48 * 0.762 = 5.21
19/05 - 31/03 + 1 = 317 * 0.71 = 32.15
                                                  37.36 TOTAL
My code does this fine, but i want to be able to choose the end date in my code i.e work out the payment to,
i.e todays date:
01/04 - 18/05  +1 = 48 * 0.762 = 5.21
19/05 - *09/12* + 1 = 205 * 0.71 = 20.79
                                                     26.00 TOTAL
An important feature is that it that the code know to work out the multiple entries in the history table (shown above)
and ((ent_seqno = (select max(ent_seqno) from lpa_history where lpa_claim.claim_no = claim_no and start_date
= (select min(start_date) from lpa_history where lpa_claim.claim_no = claim_no)))
or
(ent_seqno > (select max(ent_seqno) from lpa_history where lpa_claim.claim_no = claim_no and start_date
= (select min(start_date) from lpa_history where lpa_claim.claim_no = claim_no))))
group by lpa_history.claim_no) histHope this helps?!
