javascript radio buttons and insanity

Mar 20th, 2006

I am (as you will quickly discover) a novice javascript coder. Here is my issue. I am using a radio button, and it works fine. Then when I change some other element on the page, or hit refresh, the radio button does not remain set. You can see it in action here:

http://claytargetsonline.com/radio2.php?type=line

I have tried check to see which one is checked and every other solution I can think of. I have asked experienced programmers, and didn't want to waste more than 10 minutes of their time, but it was not obvious to them either.

I have spent about 5 hours searching the web. No avail. Help!

I did search this forum also but did not find a similar problem.

Any help woule be appreciated.

David

			<button name="refresh" type="button" onclick="refresh_window()">Refresh Chart </button>
		</td>
	</tr>
	<tr>
			<td width="297"></td>
		</tr>
</table>

</form>
<p>The problems is this. </p>
<p>Set the chart type to column and hit refresh. Everything works.</p>
<p>Now hit refresh again. Chart type changes to line.</p>
<p>I hope someone can help me with this. I am losing my mind.</p>
