why won't this error trap work?

I'm still trying to learn how to use the error trapping functions in
vlisp, here is my code:

(vl-catch-all-error-p (vl-catch-all-apply (vla-item *layers* layName)))

Right now (vla-item *layers* layName) returns "Automation Error. Key not
found" if the layer does not exist, but it works fine if the layer does
exist.

What am I doing wrong? Am I way off base with this?

Thanks,

(vl-catch-all-error-p (vl-catch-all-apply 'vla-item (list *layers*
layName)))

Of course, it is probably unneeded when you consider that the Add method
does *not* throw an error if the layer already exists. So you can simply use
the Add method to either set/retrieve the desired Layer object.

Ah, yes, this worked simple enough. Thanks!
