Hey,
I have two seperate files with a column og data about item 277 and 289 in each. Fx:
277
-1.34534
-0.98272
0.12293
etc
and
289
-4.58493
9.88273
9.33829
etc.
How do i get the second input for item 277 (i.e. -.098272) and add or subtract it from the similar second input from the list for item 289
