why do you think that should work? a hash element can only hold one
value. an array can be many values. also using an array in scalar
context (as above) is defined to return its count.

it tells you that you assigned an array and not a reference to the hash
element. this is all well covered in the various perl documents on
references including several tutorials:
perlreftut
perllol
perldsc
perlref
read those and it will (should) all make sense to you. if you still need
help, come back here with more questions.
