each of the select lists on the search page is set to use the ID column as the value.
for example:
The Course Type list is set to use the TypeID of the WADADynListtypes recordsetas the Value, and TypeName column for the label.
the label of a select list is only what the user sees. the value of the select list is what is sent when the form is submitted.
In the presentations table, what data is stored in the PresentType column? is it an id number that relates back to the types.TypeID column? or is it a text value of the TypeName.
if it is the text value, you will need to edit the select list on the search page, and change the value to use the TypeName column.
