Hi Sam,
I have tried the range notation in Set Values tool in Origin 8.1 SR3, but I couldn't reproduce the problem. What I did was as follows:
1) In Col(A) in Sheet1, Book1, entered {1, 2, 3}
2) For Col(B), I set the following in the Set Column Values:
Before Formula Scripts: range r1 = [Book1]"sheet1"!A[2:3];
Formula: r1+10
3) Run this tool, and got the following result correctly in Col(B): {12, 13}. (Note: If I used the formula: range r1 = [Book1]"sheet1"!A;
then I got the result {11, 12, 13} in Col(B).)
So, it seems okay. Maybe you can post the exact formula and the Before Formula Scripts here?
