hey, im sorry i didnt really get that since ive started using perl recently, can you explain this part to me a little @{ $height{$input}} What will my array be called then? Thanks!

:) Your array is called  $height{$input} References quick reference

[james2vegas]

That is not an array, but an array reference.

That is not an array, but an array reference.

And what do you call this "array reference", what is the name of the array it refers to ?

[Anonymous Monk]

You pronounce that height-of-$input or height-of-house or height-of-table

See Re: What are the most basic, generic aspects of programming?, Re: Perl Best Practices for naming variables, About the use of the plural form for the name of variables

[james2vegas]

@{ $whatever } de-references the array ref $whatever so you can use the reference as an array. Your data are contained in array references which you need to de-reference with @{ } to use as arrays.
