hi. i'd like to perform a check on some values. these values are being
populated into a structure that i'm then returning to flash. here's how it's
currently set up: <cfscript>     inventory[counter]['visits_total'] =
visits_total;     inventory[counter]['time_total'] = time_total;
    inventory[counter]['time_view_avg'] = time_view_avg;    </cfscript> what i'm
trying to do is check the visits_total. if that equals zero or if it returns
some undefined value, then i'd like to populate it with a value of '0'.
currently, it just returns an empty value. i tried this but it doesn't seem to
be working. <cfscript>         <cfif visits_total NEQ ''>
            inventory[counter]['visits_total'] = visits_total;
            inventory[counter]['time_total'] = time_total;
            inventory[counter]['time_view_avg'] = time_view_avg;         <cfelse>
            inventory[counter]['time_total'] = time_total;
            inventory[counter]['visits_total'] = 0;
            inventory[counter]['time_view_avg'] = 0;         </cfif>                     </cfscript> now
when i run this, no values are being returned at all. can i put a conditional
within cfscript tags? i'm not really sure where i'm going wrong as i'm
relatively new to coldfusion and my knowledge is a bit scattered on the
subject. any insight is greatly appreciated. best, fumeng.

You probably want something like this (remember, <cfscript> is a slightly
different *dialect* than cfml.

<cfscript>
if (visits_total NEQ "") {
inventory[counter]["visits_total"] = visits_total;
inventory[counter]["time_total"] = time_total;
inventory[counter]["time_view_avg"] = time_view_avg;
} else {
inventory[counter]["time_total"] = time_total;
inventory[counter]["visits_total"] = 0;
inventory[counter]["time_view_avg"] = 0;
}
</cfscript>



<cfif (visits_total NEQ "")>
<cfset inventory[counter]["visits_total"] = visits_total>
<cfset inventory[counter]["time_total"] = time_total>
<cfset inventory[counter]["time_view_avg"] = time_view_avg>
<cfelse>
<cfset inventory[counter]["time_total"] = time_total>
<cfset inventory[counter]["visits_total"] = 0>
<cfset inventory[counter]["time_view_avg"] = 0>
</cfif>

hello. thank you very much for responding to my post. i appreciate your help.
i knew cfscript had a different syntax, ironically, it is one that i'm more
used to coding in....and i still had to ask! but i got it now and understand
why it works. so, thanks for your help. much appreciated -- fumeng.
