macromedia flash flash remoting: Hello,

I have on 1 frame two calls to a function in a cfc. Both the functions is just
a simple query to the database (access mdb).
With one of them (I have also tried to remove the first, but that doesn't make
any difference) I see that flash retrieves the data correctly. But If I do a
simple trace like: trace("data is: "+result.items[0].FieldName);
it gives [undefined] . I've done this lots of times succefully. Now it doesn't
work. I checked everything on typos. What could it be???
