Rick the purpose of setting the type on the arguments going into a function, and the return variables coming out is to make the function more robust. It'll throw errors when you send the wrong type of data in an argument, or if it tries to return something that you dont expect.
You dont HAVE To use that. you can put type="any" or leave the type="" attibute out entirely if you want. I have a method i wrote some time ago that returns a query, or if the query didnt find any records it returns "norecords", which is a string. So teh function has to have type="any" or it will throw errors. In the page calling it, i know i am always going to have something returned, so i put this; <cfset datastuff = component.getAgentData( agentid) /> <cfif isquery( datastuff ) > a display table of the records goes in here. <cfelse> <p>No records were returned </p> </cfif> But the better way to do it is to use the typing - it helps make sure your methods always return the kind of data you're expecting. It would be better for me if i had written that function so it always returns a query regardless of whether or not it finds records. Thats what your <cfquery tag does - it always gives you a query object whether or not it finds records. If it doesnt find any records, it returns a query object with no records in it. I would have been better off if i'd written that function to do the same. But you dont have to.
