passing variables between pages via URL

["DelinquentMe"]

hey all,

      So what im trying to do here is use a url with two attached vars:
 /products.cfm?category=product&id=1

 first off im a total Cf newb so is this correct syntax for separating two 
variables in a URL??

 next im trying to test tese two variables then assign new values within the 
url something like this:

 <cfelseif url.category EQ "product">

 am i doing this correctly??
