I keep getting errors. Help?

Question

So I am just starting the if and if else statements.
How can I make this work. And it keeps giving me bracket errors.
If you know, please help
btnpH.addEventListener(MouseEvent.CLICK, determinepH);
function determinepH(e:MouseEvent):void
var pH:int;
pH=int(txtinpH.text)
//Do the "if" to see if they are eligible
if (pH == 6.5 && <=7.5)
lblpH.text = "NEUTRAL - FISH IN STREAMS, RIVERS AND LAKES WILL SURVIVE.";
if (pH <= 6.5)
    lblpH.text = "TOO ACID - FISH IN STREAMS, RIVERS AND LAKES WILL NOT SURVIVE.";
    if (pH >=7.5)
lblpH.text = "TOO ALKALINE - FISH IN STREAMS, RIVERS AND LAKES WILL NOT SURVIVE";
function clearLabels(e:MouseEvent):void
lblpH.text = "";
txtinpH.text = "";

Answer 1

The error originates here:
if (pH == 6.5 && <=7.5)
Correct syntax is:
if (pH == 6.5 && pH <=7.5)
In any case, your entire code should be:
btnpH.addEventListener(MouseEvent.CLICK, determinepH);
function determinepH(e:MouseEvent):void {
     var pH:int = int(txtinpH.text);
     if (pH > 6.5 && pH <= 7.5){
          lblpH.text = "NEUTRAL - FISH IN STREAMS, RIVERS AND LAKES WILL SURVIVE.";     
     else if (pH <= 6.5)     {
          lblpH.text = "TOO ACID - FISH IN STREAMS, RIVERS AND LAKES WILL NOT SURVIVE.";
     else (pH >= 7.5){
          lblpH.text = "TOO ALKALINE - FISH IN STREAMS, RIVERS AND LAKES WILL NOT SURVIVE";
function clearLabels(e:MouseEvent):void {
     lblpH.text = "";
     txtinpH.text = "";
