Uncheck one checkbox when another is checked

[boatguy]

Hello - I have the need to deselect one check box if another is selected. Here's an example:

<table width="400" border="0">
              <tr> 
                <td COLSPAN="3"><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif"> 
                  <strong><u>Hull Cleaning and Shrink Wrap (parts incl):</u></strong></font></td>
              </tr>
              <tr> 
                <td width="259"><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Do 
                  Not Acid Clean</font></td>
                <td width="99">&nbsp;</td>
                <td width="28"><input name="ACID_DONTCLEAN" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Light 
                  Acid </font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$8.40 
                  / ft</font></td>
                <td><input name="ACID_LIGHT" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Standard 
                  Acid</font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$13.00 
                  / ft</font></td>
                <td><input name="ACID_STANDARD" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Standard 
                  Acid w/ Zebra Mussels</font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$15.25 
                  / ft</font></td>
                <td><input name="ACID_WITHZEBRA" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Unit 
                  Only Acid Clean</font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$55.00</font></td>
                <td><input name="ACID_UNITONLY" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td colspan="3"><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">***Gordy's 
                  will acid wash every boat requiring cleaning unless specifically 
                  instructed.</font></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Shrink 
                  Wrap Over Rubrail Below 8'6"</font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$12.95 
                  / ft</font></td>
                <td><input name="SHRINK_OVERRUB" type="checkbox" value="yes"></td>
              </tr>
              <tr> 
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">Shrink 
                  Wrap Under Rubrail</font></td>
                <td><font color="#000066" size="2" face="Verdana, Arial, Helvetica, sans-serif">$16.95 
                  / ft</font></td>
                <td><input name="SHRINK_UNDERRUB" type="checkbox" value="yes"></td>
              </tr>
            </table>

The customer should not be able to select the ACID_DONTCLEAN checkbox and one of the other ACID_ boxes. How can I uncheck ACID_DONTCLEAN if they select something else?

I know radio buttons would be the easiest way, but the client wants to see a value passed for all of the boxes. When I post to the dB and mail script, I first set a value of Not Selected when the checkbox value isn't present.

Thanks.

something like this:

<input type="checkbox" ... onclick="if(this.checked)this.form.ACID_DONTCLEAN.checked=false;" />
