Calculations in Data Access Pages

[Dave]

- I created a database that tracks physical assets. I
built Access forms that perform simple calculations and
display the results using table values and some constants,
and would like to build the same capability in a data
access page to put the database online.
- I can't find any way to build expressions in a data
access page. How can I create text boxes with calculated
values in a data access page; or is there a better way to
create an HTML interface to the database?
Thanks.
