Dr. Frank is there also a way to have the GT Score increase automatically pop up in that column without me having to add it in there? I'm looing to only have to enter in the Pre GT score and the Post GT score and the decrease number automatically pops in the GT increase column. What you sent me was fine with the averages, but could the numner automaticall pop in the box after I put the Pre GT Score in there and the Post GT score without me having to subtract it myself. Thanks in advance
