```

}

if (checkbox2.value = true) {a1 != “”; a2 != “”; a1value != “”; a2value != “”;  
myData.a1 = a1;  
myData.a2 = a2;  
myData.SendAndLoad(“savebar2.php”, myData, “POST”);  
}  
checkbox1 = checkbox1.value;  
checkbox2 = checkbox2.value;  
checkbox3 = checkbox3.value;

myData = new LoadVars();  
myData.onLoad = function() {

You got a few of errors in your code.  
Whenever comparing variables, use the **==** operator instead of the assignment operator ( **=** );  
You are defining the _myData.a1_ and _myData.a2_ properties even before first declaring the _myData_ object, therefore they will have no value at all.  
Also, i believe you’re using sendAndLoad because you need to get a response from the PHP script. I don’t know if it’s necessary but i usually create another LoadVars object to receive that response. Something like this:

```auto
submit.onPress = function() {
	myData = new LoadVars();
	response = new LoadVars();
	response.onLoad = function() {
		if (this.writing == "ok") {
			status.text = "Datas are in the text";
		} else {
			status.text = "error";
		}
	};
	if (checkbox1.value == true) {
		myData.a1value = a1value;
		myData.a2value = a2value;
		myData.sendAndLoad("savebar2.php", response, "POST");
	}
};

```
