<!--- 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 "Maximum Value">     
        <!--- Use ArrayMax to find the largest number in the array. ---> 
        The largest number that you entered is 
        <cfoutput>#ArrayMax(myNumberArray)#.</cfoutput> 
    </cfif>     
</cfif>     
<!---- The following form provides two numeric fields that are compared when the 
    form is submitted. ---> 
<form action = "arraymax.cfm"> 
    <input type = "hidden" name = "number1_Float"> 
    <input type = "hidden" name = "number2_Float">
