url parameter question

i think this is pretty simple, but i've been struggling with it for awhile so i figured i'd ask for some help. my problem is this. i have a coldfusion page, page1.cfm, that passes a url parameter to a second coldfusion page, page2.cfm. i'm getting the value passed over fine. my problem is that page2.cfm submits to itself. when it submits to itself, i get an error that url.incidentnumber is not defined. how can i store the value of url.incidentnumber when page1.cfm sends it to page2.cfm, but not attempt to read it when page2.cfm submits to itself? thanks.

page1.cfm
<a href="Edit.cfm?IncidentNumber=#GetSingleIncident.INCIDENT_NUMBER#">EDIT</a>

page2.cfm
<cfparam name="URL.IncidentNumber" type="string">

...

<input type="button" name="SubmitForm" value="Find" onClick="this.form.submit()">

cgi.query_string contains all the url parameters passing into a page. in page1.cfm add them to the form that posts to page2

<cfoutput>
<form action="page2.cfm?#cgi.QUERY_STRING#" method="post">
</cfoutput>

CFDevHead

you could do something like this
<cfparam name="URL.IncidentNumber" type="string" default=''>

<cfif isdefined('form.IncidentNumber')>
<cfset URL.IncidentNumber=form.IncidentNumber>
</cfif>

The problem is the value on your second page isn't defined, there's a few ways to solve your issue, rob_lorentz, CFDevHead, already provided something that would work, but I thought I'd throw my 2cents in.

Another way i... add a hidden field..

<cfinput type="hidden" name="IncidentNumber" value="#form.IncidentNumber#">

this will then define and retain that value...
