I think we need more information. Merlyn is correct in that a 'my' variable cannot be referenced outside of the block, though a reference passed outside certainly can affect the value.

What I don't understand is how you can know that the value of your variable has changed unless you're doing some execution of code within your block. If you're entering a block with a 'my' variable, leaving that block to execute some other code, and returning to it, the variable is recreated and undefined on the 2nd run. Consider: 

sub a {
  my $var = 1;

  &b;                   # Can't touch $var

  eval $set_var_to_2;   # Code in this variable can affect $var

  print "$var\n";
}

If we could see some code we could explain what's going on, probably. Also make sure you're using 'strict'. This will catch lots of problems like this.
