I realize now that I am a step missing
I have my distinct list which has a number of manufacturers and each manufacturer has a selection of models. I think therefore after the list I need a results page and then a details page.
As this largely is already built in WebAssist > Database .> DataAssist Pages can the Search created be changed to a recordset to give a distinct list.
The search page is created with a Form Get: can this be changed into a recordset easily!?
