--create a new disply items on the same block
---for example name it purchase_total
--go to teh properties of this item
--go to the calculation section nad put the following values
calculation mode >>>>>> summary
summary function >>>>>> sum
summarized block >>>>>> ( block name ) in your case as u
mentioned it is "sale"
summarized item >>>>>> ( col. name ) in your case as u
mentioned it is ( the col. which represent product
purchased

note : you have also to make sure that in ur block properties to make query all records property as "yes"

OK; what prevents you to do that? Do you know how to calculate a sum? I'd use something like

SELECT SUM(column) INTO :block.item FROM some_table;

or its derivation (a WHERE clause, for example).

If you don't like that approach, loop through all block records and sum column values until you reach the last record.

But, WHY not using built-in Forms functionality? Is it because you like to reinvent the wheel?

because when i did it using built in function, the text item or text field i created will display 10 rows of text item or text field to be displayed. For the data block to be calculated I set the property to display 10rows. But for total I only want 1 row

OK; what prevents you to do that? Open Property Palette for summary item, go to Records properties and set "Number of Items Displayed" to 1 (one).

I said "for summary item", not for the whole block. There's a difference between those two terms.

How would you calculate the sum of this if a user wants to see the information of person A or information of person B. For example, items belonging to only person A or items belonging to only person B?
