Small corrections and slightly simpler.

Note: uses a,b,c matrix names because B,C are used by Mathematica.

c = Table[
xp = Map[Last, Position[a, x]];
yp = Map[Last, Position[a, y]];
If[xp=={} || yp=={} || Length[xp]≠Length[yp],
0,
Plus@@Map[b[[Sequence@@#]]&, Transpose[{xp,yp}]]
],
{y, 150}, {x, 150}]
