getting Alert component to open?

[myBad.script]

I want a message to pop up on the screen when the user clicks the 'Submit' button on a simple email form. I copied the code right out of the mm help file, and converted it to work on click instead of focus out. I get the trace message, but no alert.

function messageNull(){
if (tf_message.length<1) {
Alert(_root, "Error", "You must enter something in the message field", mxModal | mxOK);
trace("message function called");
}
}
bt_submit.addEventListener("click",messageNull);

Same result (trace, but no Alert) when I attach the function directly to the button:
on(release){
messageNull.call();
}

(The website I'm working on is coming along fine - client is pleased, almost all functions are working properly....thanks for all your help. I may get good() at this yet.)

(Originally posted in the F/MX forum, but as this is component related it was suggested I try posting in this forum)

Use Alert.show(...)!

[myBad.script]

prospero, I noticed that in some other examples and tutorials I found (never mind that I'm working with mm's own tutorial!). I changed the code as follows, but still no joy:

/*function messageNull(){
if (tf_message.length<1) {
_root.Alert.show("Please make an entry in the message area", "Error", Alert.OK | Alert.CANCEL);
trace("message function called");
}
}
bt_submit.addEventListener("click",messageNull);

I get the trace, but no alert

[myBad.script]

The answer: forget the component. It was faster and easier to build my own. (Files were smaller, too.)

if you ever do want to use the Alert.show( ... ) I think you have to include

import mx.controls.Alert;

at the top of the code file.

and you should have an Alert component in your library too. :o
