Can't assign IWitem to an array element

System

Hey,

I am trying to assign a VFE field to an element of an array using the statement:

vfeFields = IWDatacapture.getItem('/News-Articles/News/articleInfo');

However, this statement does not work properly, because when I try to do "alert(vfeFields);", I just get an empty box.
I am not sure what's wrong here. Can you even assign an IWitem object to a simple array in js?

Thanks,
Ido
