Control variables

#1
Hello,
I am doing a regression on a independent variable. The independent variable is made up by definition of a sum of other variables in my dataset. Do I have to control for these or would that be stupid?

Less is more. Stay pure. Stay poor.

If the IV is deterministically created from the other variables, they wouldn't contribute anything new. But you should tell us more, if you want additional insight.
