sorry Little Goat, been away for a few days,the check box and text box refered to in the working code appear here:
<td>Check for coupling: <input type="checkbox" id="couplingcheckbox" onclick="couplingcheck()"></td><td colspan="2"><div align="right">Total:<input type="text" name="e" id="couplingtotal" size="6" value="0"/></div></td>
and the part which doesn't work has radio buttons:
<td>Number of stops:</td><td align="right">1 - 32</td><td width="24"><input type="radio" Id="stops1" name="stops" disabled="true" onclick="allcheck()"></td><td colspan="3" align="right">Stops Total: <input type="text" name="b" id="stops" size="6" value="0"/></td>
As I said, everything works fine in Firefox, Opera and Safari, but checking the radio boxes in IE gives no response,ta, badge
