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: <mx:Label id="display" text="{(isNaN( myNumber as Number)) ? 0 : PrepForDisplay. format(myNumber) }" visible="{display. text != '0' && display.text != 'In,fin,ity. 00'}"/> Note that you need to give the Label component and id, and use that id to refer to it in your statements within braces. By the way, as you are no doubt noticing, the larger point here is that braces are not just for binding, but can contain all sorts of ActionScript. Finally, the reason that there is && instead of && is that we are inside of MXML, which is to say inside of XML, and we cannot use the & character there, but must escape it.

Just one more question. The zero works for me, but I’m sure I’ll be asked to make it blank. Any hints as to how this could be accomplished? Coming from the Flash side of things, all I would be looking to do is change the alpha value of the label to zero if the value was 0. isNaN(mynumber) ? 0 : -- Blair Cox http://www.luminult ra.com ________________________________ From: Sid Maskit <[EMAIL PROTECTED] com> Reply-To: <[EMAIL PROTECTED] ups.com> Date: Thu, 31 Jul 2008 07:51:38 -0700 (PDT) To: <[EMAIL PROTECTED] ups.com> Subject: Re: [flexcoders] NaN and Infinity showing in output - How to modify? If the format function is a custom function you have written, you could just have it check whether you like the result it is about to return, and if not, return something else. If that is not the case, I believe that you should be able to put tests into your binding statement. You could test for NaN with something like this: <mx:Label text="{(myNumber is NaN) ? 0 : PrepForDispl ay.format( myNumber) }"/> I'm not sure about infinity, but I assume that you can test for this by looking for the greatest possible value of the number. Assuming that you have set up the variable maxValue to contain that value, you should be able to do something like this: <mx:Label text="{(myNumber > maxValue) ? 0 : PrepForDispl ay.format( myNumber) }"/> If you put the two together, it would look something like this: <mx:Label text="{(myNumber is NaN) ? 0 : (myNumber > maxValue) ? 0 : PrepForDispl ay.format( myNumber) }"/> Sid Maskit Partner CraftySpace Better Websites for a Better World http://www.CraftySp ace.com blog: http://smaskit. blogspot. com/
