Here is an example of how I am using it on a feedback form.
<1-- validate form and captcha text --->
<cfif isdefined('form.sendfeedback')>
<cfset errormsg ="">
<cfset error = false>
<!--- validate the form fields --->
<cfif form.name EQ "">
<cfset errormsg = errormsg &
"<li>You must enter your name</li>">
<cfset error = true>
</cfif>
<cfif NOT isValid('email',form.email)>
<cfset errormsg = errormsg &
"<li>You must enter a valid email address</li>">
<cfset error = true>
</cfif>
<cfif form.captcha EQ "" OR NOT
application.captcha.validateCaptcha(form.HashReference,form.captcha)>
<cfset errormsg = errormsg &
"<li>The captcha code entered was incorrect</li>">
<cfset error = true>
</cfif>
<!--- validate the captcha code --->
<cfif NOT error>
<cfmail to="[EMAIL PROTECTED]"
from="#form.email#" subject="customer feedback" type="html">

been received form the web site.
