I am using LO 3.6.4 in Mac OS X 10.8.2.
In Base I have a very simple, single table assets database. In a report, I am
trying to calculate a grand total for all records.
I have a text field for each record in the report which has a calculated amount
for the record (i.e. in Report Detail there is a field called ItemTotalValue
which is bound to a function which has the formula [quantity]*[price]).
The report runs and shows a value for ItemTotalValue for each record correctly.
What I want to do is get a grand total which in effect accumulates
ItemTotalValue for the whole report.
I have successfully created a field which accumulates the price field (which is
in the table) but, I can't figure out how to accumulate a field that is created
in the report (i.e. it's not in the source table).
I have created a function at the Report level called "Calculate Grand Total Value" which has the
formula [Calculate Grand Total Value]+[ItemTotalValue]. I then bound a text box in the report footer to
"Calculate Grand Total Value". But the report footer is a blank. So, "Calculate Grand Total
Value" seems to be empty. I can't figure out how to get it working.

P.S. I can't find any rules for posting to this list. Can any one advise
where the rules are ?
Your posting of your question was what it should be: you stated
your problem clearly and contained enough information for someone to
answer it if they have the knowledge needed to do so.
I think that you are making your report more complex than it needs
to be. The secret is in the plan and design of the database. It appears
that you are using the table as the source for the report. I suggest
that you create a query based upon the table and then create the report
based upon the query.
The query contains three fields, two of which come directly from
the table: quantity and price. The third field is "quantity" * "price".
If you create the query in SQL View, this is the SQL that will create
the query (I chose to use Table1 as the name of the table. If you use a
different name for your table, replace "Table1" with your table's name
in double quotes.)
This query when run has the values you want for the report: a
column containing the quantities for each item, a column containing the
prices for the items, and a column containing of the quantity for each
item times the price of each.
In the report, you can use Report Builder's accumulation function
to add all the products in the report footer.
This is rather simplistic but it should get you started.

SELECT "quanity", "price", "quanity" * "price" FROM "Table1"
