Limit movement of symbol along axis

[FlatChat]

I have a graphic symbol being moved along the X axis programmatically via button press.

How can I limit the movement of that symbol to a certain point on the stage, e.g. along X axis?

I assume I can get the position of the symbol like:

var leftFrame_X = this.LeftFrame.x;

Is that position different from the x position shown in properties?

How would I test for that position and stop the symbol from moving further in that direction?

Like this?

function updateLF_Move_Right(){

	if(leftFrame_X != leftFrame_X){
root.LeftFrame.x+=1
	} else {
root.LeftFrame.x+=0
}

This is the code I currently have:

this.ButtonLeftFrameMoveRight.addEventListener("mousedown", LF_MoveRight_Down.bind(this));
this.ButtonLeftFrameMoveRight.addEventListener("pressup", LF_MoveRight_Up.bind(this));

var frameLeft = this;

function LF_MoveRight_Down() {
    
createjs.Ticker.addEventListener("tick",updateLF_Move_Right);
    
}

function LF_MoveRight_Up() {

createjs.Ticker.removeEventListener("tick",updateLF_Move_Right);

}

function updateLF_Move_Right(){

frameLeft.LeftFrame.x+=1

}

That shoul read:

if(leftFrame_X != some pos X){

Sorted:

function updateLF_Move_Right(){
	if(root.LeftFrame.x <= 597.3){	
root.LeftFrame.x+=1;
	}
}

function updateLF_Move_Left(){
if(root.LeftFrame.x >= 508.3){	
root.LeftFrame.x-=1
}	
}
