Proc report compute

[USHAKS]

compute ChangeN;
  _c4_ = (_c3_ - _c2_);
   endcomp;

when _C3_ is 2

and column _C2_  0

I want to see -2

but I am seeing in _c4_  0

 how to solve it.

How about

_c4_ = _c2_-_c3_;

[USHAKS]

compute ChangeN;
  _c4_ = (_c3_ - _c2_);
   endcomp;

C3 is 2020 sales

c2 is 2019 sales

when it is c3 is 13

and c2 is 15 I get -2 

Assume C3 is 2020 sales and it is 0

C2 2019 sales 2

I do not get -2

thanks,
