That has a lot of unmatched brackets, which in general makes it rather
hard to unravel what your problem might be.
I had already noticed, though, that locators have no options or syntax, to
speak of, when used as Manipulator variables. In help it says {u,
Locator}, and that's apparently IT, despite the live link from "Locator"
to the more feature-rich Locator used elsewhere. I can find no examples
where Locator is used the way you want to use it. (Unfortunately.)
