Hi all. I'm a new user (both of here and FFT Aspire) and I'm trying to import my pupil target data into Sims. I have sorted the targets and removed all those who do not study a particular subject (i.e. 70 out of 210 study art, so I have removed 140 targets), yet when I take a download from FFT, it brings in all 210 targets again. How do I get a usable spreadsheet to import into Sims please? Any ideas? Thanks!
