> What happens if it is passed in with a non-numeric value ... Wouldn't happen...the variable is used only on a page which is submitting back to itself. No other pages are utilizing it. Its default is set to 0, the formula runs, adding 1 to the value, and then it gets incremented up 1 if the "Add Another Photo" button is clicked...
Trying to work out a CF solution to allowing a user to add more CFFILE fields to a page when they click a button. When the page is submitted back to itself, the variable is upped 1, and a CFLOOP is run creating the amount of CFFILE fields specified by the variable, "Photos". Seems simple...but so far it's not working. I'm just missing something at this point...

I'd think "importance" would be subjective as to who was looking at it. I personally try to always do it like this: <cfset Photos = Variables.Photos + 1 /> But I got into the habbit of putting in Variables due to working with inherited code that lacks much of any scoping. So I'd maybe come across a page with references to Photos but have no idea if they were expecting it to come in via the URL, FORM, or whatever. In some really rare cases they might have had: <cfparam name="Photos" default="0" /> But I'd still not have any idea where they were expecting it to come from with that. All your CFPARAM is doing before the set is making Photos if it did not already exist and setting it to 0. What happens if it is passed in with a non-numeric value ...
