Help with Coldfusion/Javascript code for Adwords

Statement of problem: Trying to get Adwords Converison Tracking working on my Coldfusion web site - single site, not an affiliate. I am not a Coldfusion programmer (obviously). Google generated code to be place on the order page. Supposedly you can put the variable name in the form Google uses to generate the code instead of a "1" and then instead of counting a landing on this page as 1 conversion, you get the total amount of the order as the conversion amount. I attempted to modify the Google code to work with Coldfusion, and everything works fine (small image on order page letting user know Google Analytics is being used, and a conversion is registered).

The problem is that the conversion is counted as 1 rather than the total amount of the order. I think my problem is getting the Coldfusion variable transferred to the Javascript variable. I also don't understand the if statement without a conditional. Can someone look at my code and tell me where I have failed?

Google Code (generated by Google Adwords) - I put annatotal in as variable name where requested on their form.

<!-- Google Code for NTW Conversions Conversion Page -->
<script language="JavaScript" type="text/javascript">
<!--
var google_conversion_id = 111111111;
var google_conversion_language = "en_US";
var google_conversion_format = "1";
var google_conversion_color = "993300";
var google_conversion_label = "xxxxxxxxxxxx";
if (annatotal) {
var google_conversion_value = annatotal;
}
//-->
</script>

xxxxx&amp;script=0"/>

My Modified Code for Coldfusion - note: Coldfusion variable is order.getTotalCharges() and when I view source of resulting page gives correct amount on page. I used the CFIF because people can get to this page 2 ways, and I only want to record people who come from the page paymeth.cfm.

<!-- Google Code for NTW Conversions Conversion Page -->
<CFIF #CGI.HTTP_REFERER# contains "paymeth.cfm">
<cfoutput>
<script language="JavaScript" type="text/javascript">
<!--
var annatotal = #order.getTotalCharges()#;
</cfoutput>
-->

<!--
var google_conversion_id = 111111111;
var google_conversion_language = "en_US";
var google_conversion_format = "1";
var google_conversion_color = "993300";
var google_conversion_label = "xxxxxxxxxxxx";
if (annatotal) {
var google_conversion_value = annatotal;
}
