My first thought would be to make a copy (version 2) of the query, and instead of running several columns, only run the TD column, and maybe add criteria that only Joseph H. Cesar. And maybe without any 'total' columns to just show Joseph H Cesar. And then have it run each of his individual stats - the 1.8 on one line, and then the 0.9 on the next line/record.
And then try the SUM.
I'm not experienced enough to know why/what is causing the error. I'm just using the De-bug theory that I would use to hopefully identify where the problem is. The other day I thought I was doing things great, but having no success. When simplifying the situation, I realized that I had excluded the 'G' from the Game_ID code, and then another day I found was using 'V_G' when it needed to be 'V-G'. Very frustrating until I realized my dumb/careless mistake. And then very glad my theory was right, but had to admonish my secretary for her typing skills. Actually that was me.
