Thanks a lot for the tip, I wouldn't have figured that out. I had to tweak a little, so here what works for me:

1) Use Calculator #0 to rename the variable from dataset #0 (eg pick just 'h' with result array name 'h0') 2) Use Calculator #1 to rename the variable from dataset #1 (eg 'h' to 'h1') 3) Use "Append Attributes" while having selected both Calculator #0 and #1 to combine the output from 1) and 2). AppendAttributes1 now contains 'h0', 'h1' as well as 'h' (which one?). 4) Use Calculator #2 on AppendAttributes1 to take difference (eg h1-h0).

Without introducing step 2) 'h' was still the one from dataset #0 but that might be a Mac version variation. Like this it should always work.

Thanks a lot,

Chris

I've tried using the calculator, but cannot manage to take a difference between two variables of the same name but coming from different datasets. I tried grouping the two datasets but still I don't see how to take that difference.
