You can. That's not the cause of the error. Parameter declarations in a
function definition aren't a CF list. They're placeholders for individual,
required arguments. You're passing just a single parameter, not three, thus
the error message about the missing second argument. If the individual values
that you want to pass are in a comma delimited list within a form field, you'd
need to use a call like:
myFunction(ListGetAt(form.myField, 1),
ListGetAt(form.myField, 2),
ListGetAt(form.myField, 3))
Or rewrite the function to expect a single argument consisting of a list
containing some number of items.
