    dcard2 is an atom (a number)
dcard2 = 45 -- or some other number.
You are attempting to index into the number as if it was a sequences.

sequence s
s = {12, 45}
dcard2 = s[2]  -- now dcard2 = 45
? dcard2[2] --this will fail because dcard2 is an atom, not a sequence
  -- of length 2 or greater.
  -- dcard2 only holds a singe value.
