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 ""> ... ----- Excess quoted text cut - see Original Post for more ----- 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 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.

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. -- Regards, Andrew Scott WebSite: http://www.andyscott.id.au/ Google+: http://plus.google.com/108193156965451149543 On Thu, Apr 5, 2012 at 1:19 PM, Rob Voyle <robvoyle@voyle.com> wrote: ----- Excess quoted text cut - see Original Post for more ----- Hi Ray I put in some data and left some elements blank which should trip the error message but they are not. cfdump yields BTNSUBMIT Submit Workshop FIELDNAMES VALIDATION,WORKSHOPCODE,WORKSHOPTITLE,WORKSHOPTITLESHORT,WORK SHOPTITLEALTERNATIVE,WORKSHOPTITLEEMAIL,WORKSHOPWEB,WORKSHOPA UDIO,WORKSHOPINSTRUCTIONS,BTNSUBMIT VALIDATION 2 WORKSHOPAUDIO [empty string] WORKSHOPCODE atm WORKSHOPINSTRUCTIONS [empty string] WORKSHOPTITLE Appreciative Transitional Ministry WORKSHOPTITLEALTERNATIVE [empty string] WORKSHOPTITLEEMAIL [empty string] WORKSHOPTITLESHORT [empty string] WORKSHOPWEB [empty string] On 5 Apr 2012 at 5:44, Raymond Camden wrote: ----- Excess quoted text cut - see Original Post for more -----
