As previously stated, ideally you wouldn't store calculated data, however if
you still feel you need to store this information it is pretty straight
forward:

Table.Field = Forms!YourFormHere!FormControlHere

The form I use to enter purchasing data calculates a total cost per order,
but it doesn't put this info into the data table. How do I get it to do this?
(All the other data from the form goes to the corresponding field in the
table)
