No problem, I think I'm just misunderstanding the instructions to some extent.
Right - I've now added a recordset to my product update and insert pages, and this recordset just selects * from my Options table as I wish to use all of the options.
So, the next step is:
Once the recordset is in place on the page you will need to add the input to record the values of this secondary table. In regards to the example above you can add in a checkbox."
Presumably I just add a checkbox to the update/insert pages... then repeat this - but what I'm unsure about here is what I link the checkboxes to ?
