We have carefully characterized the low-temperature magnetotransport of a series of samples of the metallic glass (${\mathrm{Fe}}_{1\mathrm{-}\mathrm{x}}$${\mathrm{Mn}}_{\mathrm{x}}$${)}_{75}$${\mathrm{P}}_{16}$B ${}_6{}^{}{}_{}{}^{}\mathrm{Al}_3^{}{}_{}{}^{}$. We find that both localization and electron interactions are important, but the variation of the magnetoresistance with x indicates that this amorphous metal will only satisfy scaling theories which include spin fluctuations.
