%Elem / qualified data structure problem

I am not able to get the %Elem function to work with the array 'Q' in the
following code.
I believe the problem is caused by 'Q' being in a 'doubly qualified' data
structure, but wanted to see if anyone else sees another/different error in
what I am doing before I give up.

>From compile listing:
(Line 588 is a 'test' line inserted to show that the syntax
'Qty4LY.Qty4Wk(1).Q(1)' is valid and that 'Q' is recognized as an array)
058800         N8D0 = Qty4LY.Qty4Wk(1).Q(1);
058900         Idx2 = %Elem(Qty4LY.Qty4Wk(1).Q);
======>                                  ab
*RNF0312 20 a      058900  A right parenthesis is expected but is not found.
*RNF5377 20 b      058900  The end of the expression is expected.

059300         For Idx2 = 1 to %Elem(Qty4LY.Qty4Wk(1).Q) by 1;
======>                                           ab
*RNF0312 20 a      059300  A right parenthesis is expected but is not found.
*RNF5429 30 b      059300  The syntax of the FOR statement is not valid.
059600            If Idx2 <= %Elem(Qty4LY.Qty4Wk(1).Q);                     
======>                                         ab                          
*RNF0312 20 a      059600  A right parenthesis is expected but is not found.
*RNF5377 20 b      059600  The end of the expression is expected.

Explanation/clarification:
Lines 590-592 were comments.
When I try this without the '(1)' I get an error telling me that I do not
have enough indexes specified. 
>From the errors I am getting I would guess that the %Elem function is
incorrectly evaluating its parameter as '(Qty4LY.Qty4Wk(1)'.
I know I can get around this by hard coding the # of elements, but I wanted
to make the code more easily maintainable.

Anyone see anything I am doing incorrectly that would cause these errors, or
is this another BIF that does not work with this kind of data structure?

TIA
