Since you are refering to one element of the hash there is a $.

Can't help you with the {cell} someone else?

whitespace is your friend.
This doesn't make any sense to me.
i don't see how {cell} can be anything.
Do you perphaps have an extra } is it actually written as
@{$info{$loggedin}{cell}}
@{$info{$loggedin}} refers to the array held in the value of $info{$loggedin};
Example
$info{$loggedin}=[1,2,3,4,5];
if i wanted to address that array I could write
foreach ( @{$info{$loggedin}} ) {
...
}
