Problem with the function OFFSET
 

I am using the function OFFSET in a file to look for the values in another
file. But when I close the two files and later I open only the file where
this the function OFFSET, appears me the mistake #VALUE. Para that the values
come correctly, I have to open the two together files. Does anybody know how
I can solve this problem of link? Because the file should be opened daily,
but without opening the origin of the data.

Thanks
