  <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 --->
    <p>The largest number that you entered is
    <cfoutput>#ArrayMax(myNumberArray)#.</cfoutput>
  </cfif>
