Hi,
I've created a file according to a turorial, but I got some errors when I have it try computing the results. I can't see why the error occurs (it says a variable is undefined but it is set up jsut like in the tutorial form what I can judge).
Is ther a way to compare two files? Either by having them open side by side, or even better, exporting them in a way where I then can write something in Excel (or similar) that marks the differences?
Thanks in advance for any help
