If the sequence is not initialized or has less elements than the element you 
are trying to reference, it doesn't work.  You have to set up the sequence 
to have the correct number of elements.

e.g.
sequence seq
seq = {1,2,3,4,5}  -- five elements
seq[6] = foobar     -- error

try:
sequence seq
seq = repeat(0,6)  --set the number of elements up at the start
seq[foo] = bar

or

sequence seq
seg = {1,2,3,4,5}  --sample sequence
seq = append(seq,foobar)  --apend element
