Variable not there

I have a root file which has a variable calculated by me apart from all other variables which was there in the original root file from which I calculated this variable. Now when I do make class then in the header file I dont see this variable. But I can draw this variable interactively and do everything else. any clue why this is happening I am also attaching the code which was used to calculate this variable.Thank you
