Complex SQL Update Problem

Question

I have a situation where data display depends on the value of
three field variables, say Level1, Level2 and Level3. The data in
the DB has the values for these 3 fields. The user would like to
change the data in all three fields to new values to reorganize the
data display. I need to construct a CFM script where the user can
select the 3 current values for Level1, Level2 and Level3 and
select new values for each of these. The final action is to update
the DB substituting the 3 new values for the 3 old values.
I am not sure how to go about displaying the old values in
Select lists and the new ones in other Select lists to make the
process fairly easy. The data for the old and new values are
available to me in a table with just these values for retrieval and
display and the modifications are made to a different table.
Any assistance would be appreciated. Thanks,
Warren

Answer 1

Use as few form fields as possible. In other words, don't do
this,"displaying the old values in Select lists and the new ones in
other Select lists "
Either show the existing value as html output or use the
selected attribute of cfselect. In either case, you will only need
one dropdown.
