Greetings-

I am trying to subtract x-i. Both variables have values between 1-26. I want for the result to always be positive; i.e. if i is bigger than x, then the difference to be subtracted from 26. For example x=3, i=10 x-i=19.. Can I do this with the formulas or should I write a vb script? I am new to vb, any help is greatly appreciated.

Hi Sean,

I think this does what you want, if I understand correctly.
Where your x value is in column C & your i value is in column D.
The second formula is with 26 in cell B1.

=IF(C2D2,26-(C2-D2),D2-C2)
=IF(C2D2,B1-(C2-D2),D2-C2)
