To make it so that you are inserting the name rather than the id you will need to add in another recordset to the page. The recordset will have to filter results from the table that is used to populate this particular select list.
The steps are to open the page and add a new recordset, select the table that is populating this particular dropdown menu. At the bottom of the interface use the filtering options to filter on the id column with a form variable, then enter the name of your dropdown list that you are getting the id from.
Once you have the recordset on your page you can then update the insert server behavior to make use the column from this recordset for the name rather than inserting the posted value from the dropdown.
