We present a CO and atomic fine-structure line-luminosity function analysis using the ALMA Spectroscopic Survey (ASPECS) in the Hubble Ultra Deep Field. ASPECS consists of two spatially overlapping mosaics that cover the entire ALMA 3 mm and 1.2 mm bands. We combine the results of a line-candidate search of the 1.2 mm data cube with those previously obtained from the 3 mm cube. Our analysis shows that similar to 80% of the line flux observed at 3 mm arises from CO(2-1) or CO(3-2) emitters atz = 1-3 ("cosmic noon"). At 1.2 mm, more than half of the line flux arises from intermediate-JCO transitions (J(up) = 3-6); similar to 12% from neutral carbon lines; and
