Firstly, avoid using <cfselect> - you're better to use a real <select> tag.
here's your code rewritten slightly.
<select name="categoryid" onchange="javascript:window.location.href
='selectest.cfm?cid=' +
document.form1.categoryid.options[document.form1.categoryid.selectedIndex].value
">
<cfoutput query="getcategory">
<option value="#getcategory.categoryid#">#getcategory.category
#</option>
</cfoutput>
</select>
<select name="productid">
<cfoutput query="getproducts">
<option value="#getproducts.productid#">#getproducts.productname
#</option>
</cfoutput>
</select>
[javascript might be a bit iffy; check it first. if it don't work, call a
function to achieve your end result]
But are you wanting the user to change page URL when they change the value
in the first select, or are you wanting to change the content of your
second list based on the current value of the first list? If the latter,
remove the onchange code from that first select, and use the custom tag
<cf_twoselectsrelated> instead (http://www.geocities.com/thanny/ ).
alternatively you could try this custom tag cf_jselect, which i've not
used:

Subject: [ cf-dev ] how to transfer
variables?

Hi,
I am a beginner for CF. I want to have two List Menus in a form, and the
second one will be decided by the first one. I wrote a test page, but it
doesn't work. Could anyone tell me how to do that. Thanks a lot.
My code is followed:
<cfinvoke component="opps_func" method="getcategoryinfo" returnvariable
="getcategory">
<cfif IsDefined("url.cid")>
<cfinvoke component="opps_func" method="getproductinfo" returnvariable
="getproducts">
<cfinvokeargument name="cid" value=#url.cid#>
</cfinvoke>
<cfelse>
<cfinvoke component="opps_func" method="getproductinfo" returnvariable
="getproducts">
</cfif>
.......
<cfform name="form1" method="post" action="selectest.cfm">
<p>
<cfselect name="categoryid" query="getcategory" value="categoryid" display
="category"
onchange="javascript:window.location.href='selectest.cfm?cid=#categoryid#'
"></cfselect> <------Here, it seems illegal to transfer variable like
this
<cfselect name="productid" query="getproducts" value="productid" display
="productname"></cfselect>
</p>
</cfform>
.....
