with the ListLen function to determine the number of fields on the form.

<CFIF Isdefined("Form.Submit")>
<CFIF Form.Submit is "More">
<CFSET FormElem = ListLen(Form.Fieldnames)>

enter into an array.<BR>
If you would like to enter more than two numbers press the <b>more</b>

The following code initially creates two fields and then adds fields
if the user presses the MORE button. Note that FormElem is initialized to
two at the beginning of this code to indicate that the form has two
fields.

<table cellspacing="2" cellpadding="2" border="0">
<CFLOOP index="LoopItem" from="1" to="#FormElem#">
