the tutorial is broken down into 2 part:
1) Options that do not effect price.
2) Options that do effect price.
With options that do not effect price, you can set the eCart add to cart button to create the select list for you by setting the option column to be updateable from a select list, then populate the select list with the option names.
Options that do effect price are a bit trickier. when the option effects the price, you need to create the select list manually, then use a recordset to Lookup the name of the option and the price increment value. you can use the returned values in the add to cart button.
it doesn't look like your options are effecting the price, so you can skip the other part of the tutorial.
