IIF function

Hi,

I'd be grateful if somebody could please help me out with this problem.

I actually want to write the following using the IIF statement:

<cfif temp gt 0>
<cfset label = "Over">
<cfelseif temp lt 0>
<cfset label = "Under">
<cfelse>
<cfset label = "-">
</cfif>

Note
If I output the variable label using the cfif, cfelseif and cfelse, it gives me the correct output, i.e. either "-", Over, or Under.


I tried the following to rewrite the above statement using the iif function:

<cfset label = iif(temp eq 0,DE("-"),(iif(temp gt 0,DE("Over"),DE("Under"))))>

Now, when temp eq 0, it works fine.
However, when temp is lt 0, it throws me an error message saying variable Under is undefined.
And when temp is gt 0, I get the same error message, but in this case it says variable Over is undefined.

However, if I replace Over and Under by 1 or 0 (i.e. integers) it works perfect!

Any idea how to get the output either Over or Under using the iif statement pls?

Thanks and regards,
Yogesh Mahadnac.
