Printing repeating double header with dlmwrite and for loop

I'm trying to print a '.dat' file with the code below that produces a repeating double header 776 times. The value at the end of each header line should change by +1.

 for ii = 103:878
    dlmname3 = 'Input_commands.dat';
    header={'*Elset, elset=CALIBRATED_210_FINAL_VOLUME' num2str(ii)};
        for ik = 1:776
            header2={'*Include, input=Final_element_' num2str(ik) '.dat'};
        end
    dlmwrite(dlmname3, header,'delimiter','','-append');
    dlmwrite(dlmname3, header2,'delimiter','','-append');
 fclose all;
 end

I would like this code to produce:

 *Elset, elset=CALIBRATED_210_FINAL_VOLUME103
 *Include, input=Final_element_1.dat
 *Elset, elset=CALIBRATED_210_FINAL_VOLUME104
 *Include, input=Final_element_2.dat
 *Elset, elset=CALIBRATED_210_FINAL_VOLUME105
 *Include, input=Final_element_3.dat

and so on up volume 878 and final_element_776...

However it is currently producing:

 *Elset, elset=CALIBRATED_210_FINAL_VOLUME103
 *Include, input=Final_element_776.dat
 *Elset, elset=CALIBRATED_210_FINAL_VOLUME104
 *Include, input=Final_element_776.dat
 *Elset, elset=CALIBRATED_210_FINAL_VOLUME105
 *Include, input=Final_element_776.dat

etc...

I've tried a few variations but it's never quite right. I think the problem is (ik) finishes before the second iteration of (ii) hence 776 showing up on all even lines. I know I could normally do it with one loop but I need the alternate lines to use and have different values.

I think I am missing something simple for the solution so apologies in advance for that but also a thank you in advance for any help you might be able to provide!

dlmwrite is not useful here. Faster:

dlmname3 = 'Input_commands.dat';
fid = fopen(dlmname, 'W');   % Upper-case W
if fid == -1
  error('Cannot open file: %s', dlmname3);   % Never open without a check
end 

for ii = 103:878
  fprintf(fid, '*Elset, elset=CALIBRATED_210_FINAL_VOLUME%d\n', ii);
  fprintf(fid, '*Include, input=Final_element_%d.dat\n', ii-102);
end
fclose(fid);

I've since solved this having come back to it after a little break - think I'd been staring at the screen for too long. It was a VERY simple fix as suspected. Nothing at all ground breaking but will post it on the off chance it might help someone, somewhere, someday.

 for ii = 103:878
    dlmname3 = 'Input_commands.dat';
    header={'*Elset, elset=CALIBRATED_210_FINAL_VOLUME' num2str(ii)};
    header2={'*Include, input=Final_element_' num2str(ii-102) '.dat'};
    dlmwrite(dlmname3, header,'delimiter','','-append');
    dlmwrite(dlmname3, header2,'delimiter','','-append');
 end
