I'm trying to calculate forces between particles. I defined all my variables and the equation for force, but when I plug it all in, it gives me 0 when I know for a fact it's not 0. I should be getting something like f12=-0.4, f13=-0.24, and f23=-0.5.

Basically I defined variables like x1,y1, m1 , etc. and made my force equation fij with all variables having appropriate i and j subscripts.
