Abstract: We prove that given a general collection $\Gamma$ of 14 points of $\mathbb{P}^4=\mathbb{P}^4_\mathcal{K}$( $\mathcal{K}$ an infinite field) there is a unique quartic hypersurface that is singular on $\Gamma$.

This completes the solution to the open problem of the dimension of a linear system of hypersurfaces of $\mathbb{P}^n$ that are singular on a collection of general points.
