It is my strong preference that anyone asking a question about an error post the entire stacktrace. It is like a fingerprint and makes it much faster for me and others to identify problems.
In the original post, you are using selectedValue as the parameter which will be 0 or 1, not the radiobutton itself. The rb should be in the rbg's selection property Alex Harui Flex SDK Developer Adobe Systems Inc.<http://www.adobe.com/> Blog: http://blogs.adobe.com/aharui From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Wally Kolcz Sent: Monday, March 09, 2009 8:12 AM To: flexcoders@yahoogroups.com Subject: re: [flexcoders] Find the value of a radiobutton in a radio group I think I am finding that the problem is in the nextQuestionPlease() method. The reference to questionsVS is null and I can't figure out why. Here is the function: public function nextQuestionPlease():void { questionsVS.selectedIndex=currentQuestion; } Here is the viewStack: <mx:ViewStack id="questionsVS" width="98%" height="100%" paddingLeft="10"> <questions:question1 /> <questions:question2 /> <questions:question3 /> <questions:question4 /> </mx:ViewStack> In my init I set it to 0 and it appears how it should. How can I instantiate it? ________________________________ From: "Wally Kolcz" <wko...@isavepets.com> Sent: Monday, March 09, 2009 6:43 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Find the value of a radiobutton in a radio group I am trying to make a AIR app that is a test. I have radiobuttons with a value of either 0 or 1 depending on if its correct or not. I want to pass the value to a function that keeps score. I am running into a problem on determining the value of the passed question to see if the app should add a 1 to the score or not. I keep getting 'Error #1069: Property value not found on Number and there is no default value.' when I click the button. Here is my radiobuttongroup: <mx:Label fontWeight="bold" text="1. Which layer(s) of the OSI Reference Model provide(s) for internetwork connectivity?" /> <mx:RadioButtonGroup id="group1" /> <mx:RadioButton paddingLeft="10" groupName="group1" label="Data Link" value="0" selected="true" /> <mx:RadioButton paddingLeft="10" groupName="group1" label="Physical" value="0" /> <mx:RadioButton paddingLeft="10" groupName="group1" label="Session" value="0" /> <mx:RadioButton paddingLeft="10" groupName="group1" label="Network" value="1" /> <mx:RadioButton paddingLeft="10" groupName="group1" label="Presentation" value="0" /> <mx:Button label="Next" click="testMod.checkSingle(group1.selectedValue)" /> Here is my function: public function checkSingle(answer:Object):void { if (answer.value !=0) { Application.application.score += 1; } nextQuestionPlease(); } How can I get it to find the value and determine if it should add 1 or not. Thanks.
