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
submitted. --->
<form action = "arraysum.cfm" method="post">
  <input type = "hidden" name = "number1_Float">
