Dynamic file names in nested structures

I have the following script rto retrieve values from a structure
% get fieldnames for nested structures; ZZ is a1x1 structure
sig_bassins=fieldnames(ZZ); % first level location
nom_invars=fieldnames(ZZ.ARN); % second level soil type

x = ZZ.ROM.clay1; % will return a 9x3 double variable

% now If I define:
sig_bassins(17) % returns 'ROM'
nom_invars(1) % returns 'clay1'

% and now if I try:
y = ZZ.(sig_bassins(17)).(nom_invars(1)); % returns the following error message
% Argument to dynamic structure reference must evaluate to a valid field name

% what am I doing wrong?
