Origin Ver. and Service Release (Select Help-->About Origin): 8.0pro
Operating System: vista

I wanna calculate the sum from row 3 to row 6 on the column A on the active work sheet. The follow code does not work,

int i1 = 3;
int i2 = 6;
range a = col(A)[$(i1):$(i2)];
sum(a) =

it will return on the Classic script window:
SUM(a)=--


Thank you!

By the way, if I wanna calculate the sum from row 1 to the end on the column A on the active work sheet, how can I do this by mouse instead of writting code please?

Hi EigenGoofy,

sum(...) is a function to create various statistical properties like sum.N, sum.Total, sum.Mean, etc. (Try sum.=<ENTER> in Script window to see all properties.) Therefore the way like following should work:
int i1 = 3;
int i2 = 6;
range a = col(A)[$(i1):$(i2)];
sum(a);
mytotal=sum.total;

I restarted my Origin, in the first time that I tried your code, it returned "MYTOTAL=--". Then I changed to

range a2 = col(A)[$(i1):$(i2)];
sum(a2);
mytotal=sum.total;

It returned the correct value.

Then I changed back by useing "a" for the range again. It returned the correct value again.

Although I was confused by its odd behavior, my question was finally solved. Thank you very much, Hideo!
