returning values from radio buttons

[goobydooby]

I am a novice javascript programmer.

I am trying to use radio buttons to make a choice between yes and no on a form. I then want to display the value of the checked button.

I have looked in the archives and come up with the following but in IE5 it will not display the value. Any tips or have I missed something obvious.
Many thanks in advance.

<P>

<!-- sets constraints for noise and odour with radio buttons to choose yes or no-->


Yes: <INPUT TYPE = &quot;RADIO&quot; NAME = &quot;Neighbours&quot; VALUE=&quot;true&quot; checked>

No: <INPUT TYPE = &quot;RADIO&quot; NAME = &quot;Neighbours&quot; VALUE=&quot;false&quot;>

</FORM>
<P>

<SCRIPT>
//script to use value from radio buttons to determine
//the value of the variable neighbours
//as there is only a choice between two buttons a
//simple if else statement is used

var neighbours=&quot;&quot;;

IF(document.Decision.Neighbours[1].checked)

{neighbours=&quot;false&quot;;}

ELSE{neighbours=&quot;true&quot;};

document.write(neighbours)

</SCRIPT>

I get an error when I try to use capitals for IF/ELSE. I think this code is writing &quot;&quot; - an empty string, because that's what is stored in the variable - The code you have there should be called in a FUNCTION because the way it is, it is executed the first time it is read - and the user has no chance to even press a button. aving sadi that, by rights it should have written &quot;true&quot; to the page...
seriously - try using if and else. ;-)

Yeah, it needs to be in a function. I've just worked this out on my own and that script is fine inside a function.

Also not that the VALUE attribute is unnecessary as the script accesses radio[1], the second button in the array and does not use the true/false values in VALUE.

I say this because if you try to use more than 2 buttons this script will not work by accessing the VALUE, a mistake I made and wasted 1/2 a day on.
