This suggestion is a misuse of the variable_set/get methods as a 
resolution to the OP's question.  Store the serialized data in a 
$_SESSION['mymod'] data and then set the default values of your new 
form using the unserialized data from $_SESSION['mymod'].  However, if 
you have sensitive data you'll need to encrypt  and decrypt it as well 
as serialize the data.
