Looping through Structure Elements

I have this code, where I am trying to loop through structure elements.
year2 = struct('Twelve',1,'Thirteen',2);
fieldmonths = fieldnames(month2);
fieldyear = fieldnames(year2);
for i = 1:numel(fieldyear)
for j = 1:numel(fieldmonths)
temp1 = Electrical.(fieldyear{i}).(fieldmonths{j})(1,1);
Anyone know why this is telling me that Electrical.Twelve.February doesnt exist?

Because you are referencing Electrical.Twelve.February before it's created.
I'm not sure what your code is trying to do, but try replacing the temp1 line inside the loop with this:
This will build an empty structure.

@Franco: But the error message tells you unequivocally, that Electrical.Twelve.February does not exist. Perhaps the is no "date_4(i,3) == 12". While you can check this using the debugger, we can only guess these details.
