If the only parameters you need are fields, then use Afields() to get the field list and put them into a grid with a checkbox in one of the columns. Of course you can also use a listbox with MultiSelect ON and let users choose them. They can even 'move' them to a second listbox (like choosing fields when designing a view) for an easy-to-use interface.
