Hi,
You are accessing "Inozx" variable from the struct "handles" even though you have not assigned it to the struct.
I have commented the change below:
for cntdsply = 2:cntSecury
nwItmsNox = dBsecury{cntdsply,1};
Inox = num2str(nwItmsNox);
Inozx = strcat('Ino',Inox);
% Change "handles.Inozx" to "Inozx"
set(Inozx,'String',nwItmsNox,'ForegroundColor','Blue');
end
