[NeoTurtle]

I have this:
_____________
<CFPARAM NAME=&quot;Attributes.width&quot; DEFAULT=&quot;150&quot;>

(more code)
...
(more code)

<CFSET tw = #IIf(IsDefined(Attributes.width), DE(&quot;#Attributes.width#&quot, DE(&quot;100&quot)#>
_____________
and I get this error:

Error Diagnostic Information
Parameter 1 of function IsDefined which is now &quot;150&quot; must be a syntactically valid variable name

The error occurred while evaluating the expression:


tw = #IIf(IsDefined(Attributes.width), DE(&quot;#Attributes.width#&quot, DE(&quot;100&quot)#



The error occurred while processing an element with a general identifier of (CFSET), occupying document position (180:3) to (180:86).

Thanks in advance,

The problem your code faces is that it tries to deley the evaluation of attributes.width in the second parameter of the Iif function. This does not work out, since the second expression is evaluated due to the presence of # sign , and the original expression (IsDefined(Attributes.width)) does not get a chance to be evaluated.

It would be a better option to use CFIF...CFELSEIF statements in this case, eventhough they increase the number of code lines
