Subject: using variables for the hash name and key name


I'm trying to call a value from a hash using variables for both the hash
name and the key I'm trying to call

So I've got a hash like this

  hash_name = {
    "key_name_1" => "value_name_1",
    "key_name_2" => "value_name_2",
    "key_name_3" => "value_name_3",
  }

and earlier in the script I have two variables:

@hash_name_var, which looks like it's equal to hash_name

  (this statement is true, 'hash_name' == @hash_name_var)

@key_name_var, which looks like it's equal to key_name_1

  (this statement is true, 'key_name_1' == @key_name_var)


So, I'm trying to get the value out of the hash with

@hash_name_var[@key_name_var]

but this doesn't work

However, hash_name[@key_name_var] does work, so since
'hash_name' == @hash_name_var it makes me think I need to find
a way to make:

@hash_name_var == hash_name

instead of

@hash_name_var == 'hash_name'
