If you have found all the letter values but are struggling to fill the grid, these two observations should help a lot:
a) Since the 2nd digit of the entry at 1acr can only be 1 or 4, the first digit of the answer to 2dwn cannot go in row 1.
b) If the 3rd digit of the answer to 35acr were the 3rd digit of the entry, that would force 23d which in turn would force the final digits of the entries for 29acr and 33acr resulting in an impossible situation for 24dwn.
