The error message says, that the division operator "/" was applied
between string and integer number, which obviously don't work.
As the previous addition (Team1Off + Team2Def) didn't failed, both of
these items are probably strings.
If they are number literals, you can simply use int(Team1Off) + int(Team2Def)
Also note, that "/" means integer division by default (until python 2)
- i.e. the remainder would be discarded;
you can enforce float division by making at least one operand floating
point number: some_int/2.0
