A good debugging technique here is to do this.
<cfloop list="#variableNames#" index="items" delimiters = ",">
<cfoutput>#items#</cfoutput>
Then you can see if that matches what you see in your form.
And you get the error, in your second example, because it doesn't exist in
the form scope. Which is why you need to do the strucyKeyExists, but I
think you knew that.

Hi Ray
Still no go.
Just to avoid confusuion I changed the index to items so I don't get confused
with variable scope.
<cfloop list="#variableNames#" index="items" delimiters = ",">
and then
<cfif structKeyExists(form, items) and form[items] is "">
doesn't generate any appropriate error messages when an entry is ommitted.
When I just use
<cfif form[items] is "">
I get the scope error (same if I use variables[items]
Thanks for you help on this.

Hi Ray
Here is the complete code.
This validates form entries and creates an error message. this works fine I am
just wanting to get rid of the "evaluate"
<cfset variableNames=list="
workshopCode,
workshopTitle,
workshopTitleShort,
workshopTitleEmail,
workshopWeb,
workshopInstructions
">
<cfloop list="#variableNames#" index="variableNames" delimiters = ",">
<cfset trimVariable=reReplace(variableNames,chr(10),"", "all" )>
<cfset trimVariable=reReplace(trimVariable,chr(13),"", "all" )>
<cfset "error#trimVariable#"="">
<cfif evaluate(variableNames) is "">
<cfset "error#trimVariable#"= "<h5>This item can not be
blank</h5>">
<cfset error="1">
</cfif>
</cfloop>
Thanks
Rob

Evaluate isn't as slow as it used to be. That being said, you can use
the Variable scope like a struct
<cfif variables[variableName] is "">

Hi folks
I have a list of variables that I want to validate.
<cfloop list="#list#" index="variableNames" delimiters = ",">
I can get it to work fine using evaluate.
<cfif evaluate(variableNames) is "">
However most folks say evaluate is a performance hog and should be avoided.
so what is the alternative?
Thanks
Rob
