I have a report and I need to divide from the above data - the 2 record by
the 1 record(invoice amt) really need to get the %
change((14,500/14,065)-1)/100=3.09% - and then the same thing for the next
two records, the date and the job # match for these records so not sure if I
do a dsum???what it should look like and where on the report to put
it????-report footer?? in detail section??

thanks for helping in advance??

Try this --
SELECT babs.Job, babs.System_Date, babs.Customer_Code, babs.Customer_Name,
babs.Invoice_Amt, babs_1.Customer_Code, babs_1.Customer_Name, babs_1.Invoice,
babs_1.Invoice_Amt, (([babs_1].[Invoice_Amt]/[babs].[Invoice_Amt])-1) AS [%
Change]
FROM babs INNER JOIN babs AS babs_1 ON (babs.System_Date =
babs_1.System_Date) AND (babs.Job = babs_1.Job)
WHERE (((babs.Invoice) Is Null) AND ((babs_1.Invoice) Is Not Null));

Now I do not think that the invoice will always be null for the other set.
Also I am not clear on how to write SQP - I usually just creat a select query
in design view- can you decipher below if possible on what to put in design
grid.

The calcuation would occur where the JOB # and the DATE are the same - see
previous post for calc.

thanks sooo much for helping ,
