Hello experts
please help.

below is my code

<cfquery name="selectid" datasource="ds">
      SELECT ID FROM TBL
</cfquery>
<cfset recnumb=#selectid.recordcount#>

<cfselect name="attyorder">
      <option  value=""  />
      <cfloop index="LoopCount" from="1" to="#recnumb#">
              <option  value="#selectid.id# - #LoopCount#">#LoopCount#</option>
      </cfloop>
</cfselect>

The recordcount can be 2, can be 10 , can be any.
What i need is to prevent user to select the same number from
the select box. Any ideas?

Thanks.

Is this a trivia question?

<cfset recnumb=#selectid.recordcount#-1>

the  numbers represents the order.
Here is  what i tried to achieve. Each record from the query should has a select box with numbers from 1 to number of records. User will select number which represent the order (for future use). See the attachment how it  looks (this is a very simple version).
what i need is if you select 2 for exmp in the box for one record , you can't  select 2 for any other record
Any suggestions?pls

here it is ;)
<SCRIPT TYPE="text/javascript">

function isSelected(sb){

  var sbarr = document.getElementById("divOrder").getElementsByTagName("SELECT");

  for (i=0; i<sbarr.length; i++)

  if ((sbarr[i] != sb) && (sbarr[i].value == sb.value)) return true;

  return false;

}



function checkOrder(sb){

  if (isSelected(sb)) sb.value=oldVal;

}



var oldVal;

function setOldValue(sb){

  oldVal = sb.value;

}



function selectOldValue(sb){

  for (var i = 0; i < sb.options.length; i++)

    if (sb.options[i].value == oldValue) sb.options[i].selected="selected";

}

</SCRIPT>



<div id=divOrder>

A : <select id=sel1 onclick="setOldValue(this)" onchange="return checkOrder(this)">

<option value=1 selected>1</option>

<option value=2>2</option>

<option value=3>3</option>

<option value=4>4</option>

</select><br>



B : <select id=sel2 onclick="setOldValue(this)" onchange="return checkOrder(this)">

<option value=1>1</option>

<option value=2 selected>2</option>

<option value=3>3</option>

<option value=4>4</option>

</select><br>

<option value=1>1</option>

<option value=2>2</option>

<option value=3 selected>3</option>

This function is never used in your solution and can be removed:

function selectOldValue(sb){
  for (var i = 0; i < sb.options.length; i++)
    if (sb.options[i].value == oldValue) sb.options[i].selected="selected";
}

Thanks Zvonko,

I thought

if (isSelected(sb)) sb.value=oldVal;

will not work, and thats why I added that function, then forgot to use it since setting sb.value directly was working ;)

Here is the revised version with that function...
<SCRIPT TYPE="text/javascript">

function isSelected(sb){

  var sbarr = document.getElementById("divOrder").getElementsByTagName("SELECT");

  for (i=0; i<sbarr.length; i++)

  if ((sbarr[i] != sb) && (sbarr[i].value == sb.value)) return true;

  return false;

}



function checkOrder(sb){

  //if (isSelected(sb)) sb.value=oldVal;

  if (isSelected(sb)) selectOldValue(sb);

}



var oldVal;

function setOldValue(sb){

  oldVal = sb.value;

}



function selectOldValue(sb){

  for (var i = 0; i < sb.options.length; i++)

    if (sb.options[i].value == oldVal) sb.options[i].selected="selected";

}

</SCRIPT>



<div id=divOrder>

A : <select id=sel1 onclick="setOldValue(this)" onchange="checkOrder(this)">

<option value=1 selected>1</option>

<option value=2>2</option>

<option value=3>3</option>

<option value=4>4</option>

</select><br>



B : <select id=sel2 onclick="setOldValue(this)" onchange="checkOrder(this)">

<option value=1>1</option>

<option value=2 selected>2</option>

<option value=3>3</option>

<option value=4>4</option>

</select><br>



C : <select id=sel3 onclick="setOldValue(this)" onchange="checkOrder(this)">

<option value=1>1</option>

<option value=2>2</option>

<option value=3 selected>3</option>

<option value=4>4</option>

</select><br>

</div>

Hi ,
sorry it took a while to response, was away :( on vac :)
This code is working, thanks. However, if you check above image , i need to pass a person's id along with the number(from selectbox) to another form for processing.
where or how i can place this id? Look at this two pieces of code:
1. <cfquery name="selectid" datasource="ds">
      SELECT ID FROM TBL
</cfquery>
<cfset recnumb=#selectid.recordcount#>
<cfselect name="attyorder">
      <option  value=""  />
      <cfloop index="LoopCount" from="1" to="#recnumb#">
              <option  value="#selectid.id# - #LoopCount#">#LoopCount#</option>
      </cfloop>
</cfselect>
this gives me needed variable ID-Order , but doesn't restrict repetings in order.
2. <select name="attysend" onclick="setOldValue(this)" onchange="checkOrder(this)">
   <option  value=""  />
 <cfloop index="LoopCount" from="1" to="4">
        <option  value="#LoopCount#" id="#LoopCount#" >#LoopCount#</option>
     </cfloop>
 </select>

this one gives me needed restriction on select but  no ID, i tried different approaches  and nothing works.
any ideas?
