Hey there! :be:

I’m sending a variable to a PHP file like this:

```auto
myVars = new LoadVars();
  myVars.nLetter = _root.poster;
  myVars.sendAndLoad("postIt.php",myVars, "POST"); 

```

And I was wondering if it’s possible to make a function witch checks if  
\_root.poster is equal to the last variable sent, if so, don’t send, else send the new variable…

How can this be done? Any help would be nice 🙂
