Simple calculation


I am creating an assets management app at the moment and am not sure what to do in order for a total to be put into a DA input field. Could I possibly use an eCart object?

Field 1 has the unit cost
Field 2 has the qty
In field 3 I would like a total automatically calculated as unit cost x qty to be inserted on submit.

Any pointers or help would be much appreciated.

You probably don't need a cart.

First, you probably don't want to insert into field3. If field3 by definition is equal to field1*field2, then storing it at all is just an opportunity for an error. Just store field1 and field2 in the database and if you want to use all three use a query like:

SELECT *, (field1 * field2) AS field3 FROM table

and even though you only stored field1 and field2 you can always get the value of field3 in your results.
