that's messy i think. i would loop through the cgi.http_referer.
<cfset pCodeValue="No pCode value Found">
<cfloop list="#cgi.http_referer#" index="i" delimiters="&">
<cfif Find("pCode",i) and ListLen(i,"=") eq 2>
<cfset pCodeValue=ListGetAt(i,2,"=")>
</cfif>
</cfloop>
<cfoutput>#pCodeValue#</cfoutput>
With this, it doesn't matter what the length of pCode value, you will get the exact
number returned.

Ooops I'm sorry, I'm actually trying to extract this value from the
cgi.HTTP_REFERER variable. Here's what I'm currently using:
<cfif (isDefined("cgi.HTTP_REFERER")) AND (FindNoCase("pCode=",
CGI.HTTP_REFERER))>
<cfset variables.pCode = mid(cgi.HTTP_REFERER,FindNoCase("pCode=",
CGI.HTTP_REFERER)+6,2)>
</cfif>
My only problem is when the pCode starts to vary in length - they're not
going to be two digits forever. Thanks for any help you can provide.
Adam.
