Retrieve variable value set in each loop, outside of the loop

Question

I need to get the value of a variable that's set in an each loop in jQuery. Here's what I have so far:

$('#conservatory_size .eva_toggle').each(function(){
  if($(this).hasClass('active')){
     var conservatory_size_total = $(this).data('price');
  }
});
alert(conservatory_size_total);

The value is there and it works, because if I call the alert inside the each loop it shows the correct price. But out of the loop the variable doesn't even alert.

Any ideas?

UPDATE

If I do what you have said, the IF statement is blatantly working, declaring the variable before the loop.. is not.

$('#conservatory_size .eva_toggle').each(function(){
            if($(this).hasClass('active')){
                var conservatory_size_total = $(this).data('price');
                alert('Has class.');
            }
        });
        alert(conservatory_size_total);

$('#conservatory_size .eva_toggle').each(function(){...

Try to declare your var outside the loop

var conservatory_size_total;
$('#conservatory_size .eva_toggle').each(function(){
  if($(this).hasClass('active')){
     conservatory_size_total = $(this).data('price');
  }
});
alert(conservatory_size_total);

It just says 'undefined'.
