RE: [flexcoders] NaN and Infinity showing in output - How to modify?
I don't recommend writing complicated binding expressions, because you have to use < in place of <, > in place of >, and & in place of &.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Hmm, sorry the last post left a part out, it was shown lower down: Adding the ³² as you stated, returns an error for mx:Label, ³>² or ³/>². The zero is what is display in the application, if I could provide a short string instead, it would be ideal. Even if the initial default text of the label was ³whatever² until a calculated value was entered. But there are many, many of these calculations to perform and I would like to find the simplest answer.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?
Actually, if you are just going to hide the label field, you can just have it display the result of the formatting, and put the checking for NaN and infinity into the setting for visibility. Since you are going to hide the label and it has a value you don't like, you don't really care what it is displaying when it is invisible.

Try something like this: Note that you need to give the Label component and id, and use that id to refer to it in your statements within braces.

Subject: [flexcoders] NaN and Infinity showing in output - How to modify?
I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.
Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?
I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity.
How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.
Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.
{Number( userInput. text) * (1 +
Number(otherUserInp ut.text)) * 1 /
Number(otherOtherUs erInput.text) }
The answer is output to:
Thank you, any assistance you can provide would be welcomed.
