Posted - 07/25/2013 : 09:42:02 AM Untill two day ago, I used standard functions (one set of sites, two set of sites ecc..) to fit some curves. It worked perfectly. Now when I try to use these functions the software shows the following error: A valid Function has not been selected. My question is, how to restore the standard function?
