I receive this error: 

I don`t know how to solve it and where to look for... Actually, I checked any root I could guess... I wonder if the problem is in my model or in excel file.

I appreciate your quick reply,

Hi

this means that the array you use in SheetRead and the range you gave are not in sync

Thank you Alex;

But I have checked it several times and I am defining the same size area in excel and .dat section.

Do you know any solution?

It is just a single dimensional array... Can you please tell me how I can write it in .mod section?! then probably it works....

Thanks in advance

Hi

have you had a look at the example oil in CPLEX_Studio126\opl\examples\opl\oil ?

Have a look at oilSheet.dat

regards
