<h3>ArraySum Example</h3> 
This example uses ArraySum to add two numbers.<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. ---> 
        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"> 
    <br> 
    <input type = "submit" name = "submit" value = "Add"> 
</form>
