Changing Properties via AS3

I'm trying to write the proper AS3 script to change the properties of a single movie clip called blueMC. I'm using input text fields that have instance names with a button next to them to trigger the change in the MC's properties. Here's my code thus far:

yscale_btn.addEventListener(MouseEvent.CLICK, yScale);
xscale_btn.addEventListener(MouseEvent.CLICK, xScale);
alpha_btn.addEventListener(MouseEvent.CLICK, alphaChange);
rotate_btn.addEventListener(MouseEvent.CLICK, rotateChange);
xloc_btn.addEventListener(MouseEvent.CLICK, xLoc);
yloc_btn.addEventListener(MouseEvent.CLICK, yLoc);

function yScale(event:MouseEvent):void {
blueMC.scaleY = yScale.text;
}
function xScale(event:MouseEvent):void {
blueMC.scaleX = xScale.text;
}
function alphaChange(event:MouseEvent):void {
blueMC.alpha = alphaChange.text;
}
function rotateChange(event:MouseEvent):void {
blueMC.rotate = rotateChange.text;
}
function xLoc(event:MouseEvent):void {
blueMC.x = xLoc.text;
}
function yLoc(event:MouseEvent):void {
blueMC.y = yLoc.text;
}

When I test the movie, I get the following errors: 1023: Incompatible override and 1021: Duplicate Function Definition.

I don't see anything duplicated in my functions, they all seem pretty unique other than the format. Can you help?

you're too confused to help.

It was an old Flash MX file that I then saved as a Flash CS3 file. Will that not work? I'll try taking all of the content out of the file and put it into a new AS3 file.

thanks.

the file you posted has as1 code in it. where's the code you posted in this forum?

Here's the code:

yscale_btn.addEventListener(MouseEvent.CLICK, yScale);
xscale_btn.addEventListener(MouseEvent.CLICK, xScale);
alpha_btn.addEventListener(MouseEvent.CLICK, alphaChange);
rotate_btn.addEventListener(MouseEvent.CLICK, rotateChange);
xloc_btn.addEventListener(MouseEvent.CLICK, xLoc);
yloc_btn.addEventListener(MouseEvent.CLICK, yLoc);

function yScale(event:MouseEvent):void {
blueMC.scaleY = yScale.text;
}
function xScale(event:MouseEvent):void {
blueMC.scaleX = xScale.text;
}
function alphaChange(event:MouseEvent):void {
blueMC.alpha = alphaChange.text;
}
function rotateChange(event:MouseEvent):void {
blueMC.rotate = rotateChange.text;
}
function xLoc(event:MouseEvent):void {
blueMC.x = xLoc.text;
}
function yLoc(event:MouseEvent):void {
blueMC.y = yLoc.text;
}

If you look at my code at the beginning of this post, you'll see that all of the functions have unique names:

function yScale(event:MouseEvent):void {
blueMC.scaleY = yScale.text;
}
function xScale(event:MouseEvent):void {
blueMC.scaleX = xScale.text;
}
function alphaChange(event:MouseEvent):void {
blueMC.alpha = alphaChange.text;
}
function rotateChange(event:MouseEvent):void {
blueMC.rotate = rotateChange.text;
}
function xLoc(event:MouseEvent):void {
blueMC.x = xLoc.text;
}
function yLoc(event:MouseEvent):void {
blueMC.y = yLoc.text;
}

Per the instructions, I've encased the action in the function with the Number() function as follows:

blueMC.scaleY = Number(yScale.text);

pay attention:

the duplicate function definition messages means you have two functions with the same name. remove one.

the incompatible override is probably because you're not using the Number() function as discussed previously.

yes.

I'm still getting two errors:

1023: Incompatible override
1021: Duplicate function definition

In this line of code:

function yScale(event:MouseEvent):void {
blueMC.scaleY = yScale.text;
}

Am I supposed to declare which mouse event triggers like this:

function yScale(event:MouseEvent):void {
blueMC.scaleY(event:CLICK) = yScale.text;
}

With this I get this error:

1084: Syntax error

The problem is that text in your text fields are strings and the properties you are trying to set are numbers. Previous versions of ActinScript won't complaint about this. But this version is very strict. So you have to convert the strings to number using the Number, parseInt or parseFloat funtions.

Number is more generic, while parseInt is for integer numbers and float is used for any integer of floating point number.
