<h3>ArraySum Example</h3>
<p>This example uses ArraySum to add two numbers together.<br> </p>
<!--- After checking whether the form has been submitted, the code creates 
an array and assigns the form fields to the first two elements in 
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">
   <input type = "hidden" name = "number2_Float">
   <input type = "text" name = "number1">
   <br>
   <input type = "text" name = "number2">
