CreateJS Tick function not updating from external values. - createjs

Question

I think this might be quite basic, I'm still learning CreateJS. I won't include all the code as its a large program but basically.
Outside of my tick function I have this code:
var hitOrMiss = 'Mada';
function hit()
{
hitOrMiss = 'Hit';
//alert(hitOrMiss);
}
function miss()
{
hitOrMiss = 'Miss';
//alert(hitOrMiss);
}
When I click a button and call these they are testing ok (alerting out the values).
Inside my tick() function the values are not being picked up.
if(hitOrMiss = 'Mada')
{
var basic = 'basic';
}
else if(hitOrMiss = 'Hit')
{
if(gamePrincessBmpAnimation.x < 1000)
{
gamePrincessBmpAnimation.x += gamePrincessBmpAnimation.vX;
var basic = 'Not basic';
}
}
else if(hitOrMiss = 'Miss')
{
if(gamePrincessBmpAnimation.x > 60)
{
gamePrincessBmpAnimation.x -+ gamePrincessBmpAnimation.vX;
var basic = 'Miss Not basic';
}
}
Do I need to specify a listener, if so how should it be set up?
I have already triggered the below, Does something similar need to be added to the tick function?
createjs.Ticker.addListener(window);
createjs.Ticker.useRAF = true;
createjs.Ticker.setFPS(60);
gameStage.update();
The other if statements within the tick function are all firing, an example of which:
if (bmpAnimation.x >= screen_width - 16) {
// We've reached right side of our screen
// We need to walk left to go back to our initial position
bmpAnimation.direction = -90;
}
Any help would be appreciated! :)

Fixed this one, wasn't a createJS issue, was a silly Javascript issue, the code here: else if(hitOrMiss = 'Hit') should have been else if(hitOrMiss == 'Hit') etc.
