I am having some problems passing my array to my subroutine. 

print " enter a formula.\n";
chomp($form=<>);

@array = $form =~ /[A-Z][a-z]?|\d+/ig

$weight = getweight(@array);

sub getweight
    {
       my @weight =@_;
     }

So if the User enters like C12H22O11 when I print at array it shows C 12 H 22 O 11 but when I print or return @weight it goes back to C12H222O11 its no longer seperated do I need to do the reg expression inside the routine too? Thanks I hope someone can show me the right way
