Studies of Andromeda (M31) are important as it is the only other large spiral in the Local Group, and unlike the Milky Way we can obtain a complete census of all star formation, gas and dust in the galaxy. In this poster I present an on-going JCMT submillimetre survey: HARP and SCUBA-2 High-Resolution Terahertz Andromeda Galaxy Survey (HASHTAG) is a new 280 hour project observing the cold dust of the whole disk of Andromeda at 450 and 850µm and selected regions in CO(J=3-2). The combination of Herschel and HASHTAG observations, in addition to the application of a new SED fitting technique, PPMAP, will produce maps of the dust in Andromeda with ~
