hi…Im using php to check for existance of username. It send back to flash ‘false’ if user already exist, and ‘true’ if user does not exist.

php:

```php
if ($num > 0)//loginName already exists
{
	echo "auth=false";
}
else//loginName does not exist, so we can insert this user
{
	echo "auth=true";
}

```

This php works and sends the correct value (true or false).

AS:  
[AS]loadInfo = new LoadVars();  
added= “Begin Login Process - Please Wait…”;  
loadInfo.onLoad = function(success){  
if (success)  
{  
errorRegion=this.auth;//this outputs correctly  
if (this.auth == ‘false’)//but this wont check!  
{  
added= “”;  
errorUser=“Username already exists.”;  
}  
else if (this.auth == ‘true’)//and this wont check!  
{  
added=“You have been added”;  
}  
}  
else  
{  
added=“could not load in stuff!”;  
}  
};  
user.sendAndLoad(“userRegistration.php”, loadInfo, “POST”);[/AS]

The ‘if’ statements wont run…its like flash cant recognize what it has already recieved! why?

Can some1 take the time to check whats wrong ! thanks
