    the array. --->
    <cfif IsDefined("FORM.submit")>
       <cfset myNumberArray = ArrayNew(1)>
       <cfset myNumberArray[1] = number1>
       <cfset myNumberArray[2] = number2>

       <cfif Form.Submit is "Add">
          <!--- use ArraySum to add the number in the array --->
          <p>The sum of the numbers is
          <cfoutput>#ArraySum(myNumberArray)#.</cfoutput>
       </cfif>
    </cfif>
    <!--- This form provides two numeric fields that are added when the form is
