Not quite sure I understand what you are asking...

Am I right in assuming the following?
1) You have a form with 3 text boxes where the user enters data called Value1, Value2, and Value3.
2) You have a database table with fields named "Cost" and "Expenses."
3) You are asking how to take the data entered in the form and modify the existing values in your table.

Is that correct?
