JavaScript - Checkbox Disable Script

Depending on the radio button a user selects, I want to be able to disable the checkboxes for all the other courses. It works in IE, but I need to add scripting to address fact that Netscape does not support disable. Here's my code any ideas will be greatly appreciated:

php Code:

<head>

<body>
<form name="form1" id="form1" method="post" action="">
  <table border="0" cellpadding="0" cellspacing="2">
    <tr> 
      <td><input type="radio" name="gr1" value="Yes" onClick="Disab(1)"></td>
      <td>US History 10</td>
      <td><input type="checkbox" name="UHist10_01A" value="Yes" disabled></td>
      <td>Section 01A</td>
    </tr>
    <tr> 
      <td colspan="2">&nbsp;</td>

RE: JavaScript - Checkbox Disable Script

BTW, when all is said and done, I will be generating the table and javascript on the fly in PHP depending on what rows are returned from my database, based on which teacher logs in.

RE: JavaScript - Checkbox Disable Script

I gave up on this script because I finally figured out that the .disable is a Microsoft thing and not supported by Netscape. I was going to have to jump through so many hoops for Netscape it decided to go to a script that just pops an alert box when you try to click on more than one group of checkboxes. AND I'm generating in on the fly with a PHP script. Pretty slick. It was easy to do when I just had 2 sets of three or three sets of two, but I has several that were a mixture of ones, twos, and maybe some threes and that was tough, but I finally got it going. If anyone wants to see it, respond and I'll post it.
