RE: lost in hashes

[Mooney Christophe-CMOONEY1]

Not hard to do when dealing with references!  ;)

The problem is that you are assigning a REFERENCE TO A HASH to the HASH itself, 
because you're using '{}' when assigning to %T.

$T{d4} has the opposite problem -- it needs to be associated with a SCALAR, ie. a 
REFERENCE TO A HASH.  '()' is a LIST, not a REFERENCE.

So, switch your '{}'s and '()'s and it should do what you want it to.

Also, when you reference some field from $T{d4}, you need to be sure to deREFERENCE it 
like this:

$T{d4}->{names}

So you'll have to change that in the popup_menu.

HTH!

Hi,

I just can't see where I have missed it! 



  %T = {
         d4 => (
                 names => [ "", "Ron",   "Tony",  "Jeff",  "Scott",  ],
               ),
       };


  print $query->popup_menu( -name    =>'Test',
                            -values  => $T{ "d4" }{ "names" },
                            -default => ''
                          );

Do you?


Thanks for Your help!!

Jerry
