[SOLVED] Gravitational force between 2 people

OK, this is my first time doing this so I'm completely lost.

1. The problem statement, all variables and given/known data
Find the force of attraction between a 60kg student and another student of mass 80kg, 1.4m away.

2. Relevant equations
G = 6.67 * 10$$^-11$$ Nm$$^2$$/kg$$^2$$

Fg = $$\frac{Gm_1m_2}{r^2}$$

3. The attempt at a solution
I tried [6.67 * 10^-11 (60kg)(80kg)] / 1.4m

But I'm wrong.

r^2, mate; not r.
