Hi,

I don't know if there is anyone on the list tried to keep all the form
labels aligned all the way on the left. I could assign it to aligning on the
left, but what I really want is have every single label, start from the
horizontal coordinate from x="0" instead of having the last character of each
form item aligned to the left. Now it looks like some letter head address, and
I don't want it that way.

Attached is my code, and I would appreciate it if anyone can give me tips on
what I have overlooked.

<mx:Form y="20">
<mx:FormItem label="Your Name:" fontWeight="bold" textAlign="left">
<mx:TextInput id="your_name"/>
</mx:FormItem>
<mx:FormItem label="Your Birth Date:" fontWeight="bold"
textAlign="left">
<mx:TextInput id="birth_date"/>
</mx:FormItem>
<mx:FormItem label="One Line to Describe Yourself:"
fontWeight="bold" textAlign="left">
<mx:TextInput id="yourself_intro"/>
</mx:FormItem>
</mx:Form>

It looks like you are declaring both local and global variables with the same
names. In this case, the local declarations within the functions are overriding
the global variables. Instead of using var selArr;Array = [] in your
checkBox_change function, remove the 'var' keyword and just use:
selArr = [];

I think you can also delete the global selArr2 and selArr3 variables since
they only appear within the checkbox_change2 function and don't need global
scope. If this is not the case, then you will need to also remove the 'var'
keyword within the function as above.

I think this should help with your error messages, but post back if you still
encounter errors.

Hi,

Thanks for the reply, but the answer here now gives me errors. To make sure
that I have understood what you were saying here, I have attached the revised
version of the code below.

I see the errors on the page right away after I made these changes, and
the most obvious one is here: Severity and
Description Path Resource Location Creation Time Id
1067: Implicit coercion of a value of type Array to an unrelated type Class
and 1188: Illegal assignment to class Array. at the line where selArr:Array= []
is declared.

Have I not added something I should be adding here?

Thanks for your help.

[Bindable]private var selArr:Array;
[Bindable]private var len:int;

private function checkBox_change(evt:Event,x:Array):void {
selArr:Array = [];
var idx:int;
var len:int =
my_book.lastResult.collection.store_id.author.leng th;
for (idx=0; idx<len; idx++) {
if (x[idx].selected) {
selArr.push(x[idx].label);
}
}
}
private function checkBox_change2(evt:Event,y:Array):void {
selArr2:Array = [];
var idx:int;
var len2:int =
my_book.lastResult.collection.region_id.publisher. length;
for (idx=0; idx<len2; idx++) {
if (y[idx].selected) {
selArr2.push(y[idx].label);
}
}
var len3:int= len + len2;
var selArr3:Array= selArr2.concat(selArr);
var title:String = selArr2.length + " of " + len2 + " item(s)
selected.";
var title2:String = selArr3.length + " of " + len3 + " item(s)
selected.";
var message:String = selArr2.join("\n");
var message2:String = selArr3.join("\n");
Alert.show(message, title);
Alert.show(message2,title2);
}

You are still not declaring your selArr correctly.
The declaration [Bindable]private var selArr:Array; is an instance variable.
It is defined outside of any function and is visible to anything in your object.

In your function
private function checkBox_change(evt:Event,x:Array):void {
selArr:Array = [];

selArr is defined as a local variable visible only within the function
checkBox_change. Since the names are the same you are overriding the instance
variable. (In reality this should not have compiled properly ... your first
try of var selArr:Array = [] was the valid syntax for overriding the variable)

To fix it you just need to change
selArr:Array = [] into selArr = [];

Hi,

I did what you mentioned here, and selArr did the trick.
However, it still does not give me what I was hoping to see, which I think I
have done something wrong here with the concat().

I was hoping that the Alert box would say something like 3/5 items selected,
and list the results of both what the client has generated in selArr2 and
selArr, which was concatenated and combined into selArr3. Currently, I would
get a message that say 4/3 items selected, even though it does return me with
the items I have selected from both selArr and selArr2.

To give things a better picture, below is the complete code I have:

Thanks very much for your help.
