URL problem

hey, i'm in need of some help with my coldfusion code. this is the problem, i currently have a set up with increasing links depending on how much information is inputted into the database. this is the code im using to accomplish this feature.

<cfset max = 5>
<cfparam name="url.start" default="1">

<cfoutput query="info" startrow="#url.start#" maxrows="#max#">
#info.name# | #info.message# <br>
</cfoutput>

<cfset pages = ceiling(info.recordcount/max)>
<cfif pages gt 1>
<cfloop from="1" to="#pages#" index="i">
<cfoutput>
<a href="home.cfm?number=#url.n#?start=#val((i*max)-(max-1))#">#i#</a>
</cfoutput>
</cfloop>
</cfif>

Here is my error message:

Error Executing Database Query
and it points to this part of my code:

where number=#url.n#

I noticed that the increasing link number code works fine on the other pages i use it at but the code is a little different on the other pages i use it at because i have the link part set up like this:

<a href="home.cfm?start=#val((i*max)-(max-1))#">#i#</a>

and at the page im using it where i get the error i need it to be like this:

<a href="home.cfm?number=#url.n#?start=#val((i*max)-(max-1))#">#i#</a>

this is where i think the problem is at because i also noticed on the error page that the information is being read like this:

select name
from people
where number=12?start=1


and number in the database should be only 12 but for some reason coldfusion keeps reading the rest of the url and i think thats where the problem is....

could anyone help me? i would greatly appreciate any type of help...
thanks!!
