You could either go with jquery or use cfform's built in validation
Edit - Fix copy and paste error

<!--- sample data for testing only --->
<cfset dropDown1 = queryNew("")>
<cfset queryAddColumn(DropDown1, "Ship", listToArray("AAA,BBB,CCC,DDD"))>
<script type="text/javascript">
function validateDisipline1(frm, fld, listValue) {
var buttonValue = getSelectedRadioButton("showall");
var isOptional = buttonValue != "1";
return isOptional || listValue.toLowerCase() != "all";
}
function getSelectedRadioButton(name) {
var buttons = document.getElementsByName( name );
for (var i = 0; i < buttons.length; i++) {
if (buttons[i].checked) {
return buttons[i].value;
}
}
return "";
}
</script>
<cfform method="post">
<!--- Note, "ID" values must be unique --->
<input type="radio" name="showall" value="1" /> Yes
<input type="radio" name="showall" value="0" /> No
<cfselect name="discipline1" id="discipline1" style="width:170px;"
onValidate="validateDisipline1"
message="Please select a discipline value other than ALL">
<option value="ALL">ALL</option>
<cfoutput query="DropDown1">
<option value="#DropDown1.ship#">#DropDown1.ship#</option>
</cfoutput>
</cfselect>
<input type="submit">
</cfform>
with jquery you can do it like this:
$("#showall").click(functi
var i = $(this).val();
alert(i);
if (i == '1') {
var selectAll = $("#discipline1 option:first").val();
if ($.trim(selectAll) == 'ALL') {
$("#discipline1 option:first").attr('disab
}
}
});¿
<input type="radio" name="showall" id="showall" value="1" />
<select name="discipline1" id="discipline1" style=width:170px;>
<option value="ALL">ALL</option>
<option value="2">2</option>
<option value="3">3</option>
</select>¿
Check this:

$("#showall").click(functi
var i = $(this).val();

if (i == '1') {
var selectAll = $("#discipline1 option:first").val();

$("#discipline1 option:first").attr('disab
}
}
});¿
<input type="radio" name="showall" id="showall" value="1" />
<select name="discipline1" id="discipline1" style=width:170px;>
