I'm not sure if I'm understanding your question correctly.
Well each row has names and numbers. The index(i,5) and index(i,6) are 2 numbers which I am pulling out and adding together(As well as performing some other operations on them), then displaying the result in a different QTableModel. It seems to work just fine but for only the first row, maybe I have setup my forloop incorrectly?

I used a similar forloop to add data to the tableView from a txt file and that works with no problem. I can add a txt file full of data but I just can't perform operations on the data(Except for the first row of course).

Thanks.
