Re:

I use cfselect like following code,

"hello" shows when I use <cfif not isDefined>, it does not show isDefined,

Thanks again,

Regards,

<cfif isDefined("form.lstMylst")>

    hello

</cfif>

<td>
  <cfselect name="lstMylst" id="lstMylst">

         <cfoutput query="myQuery">
         <option value="#MyQuery.MyID#"
            <cfif (isDefined("form.MyID") AND form.MyID EQ myQuery.MyID)>selected="selected"</cfif>> #MyQuery.MyName# </option>
            
         </cfoutput>

  </cfselect>
