Invalid column name for the group attribute.

Hi,

Please help, I m struck with this for the past 2 days.

Basically i have  big query and with cfoutput and group attribute; i m displaying hte results..

It has 4 levels of grouping.

Also, the grouping column will be different every time the user choose it.so I'm building an array to do it.

Suppose the user choose only 3 columns, I'm manually adding the 4th column so that array has 4 values all the time.

At time, i m getting this error, the column name is invalid.

Your help is highly appreciated.

<cfoutput query="mtburbycust" group="#lstSQLOrderBy[1]#">

          <cfif currentRow EQ 1>

              <cfset rowColor2 = 'CECE9E'/>

         <cfelse>

             <cfif isdefined('Prevcolor')>

                <cfif comparenocase(Prevcolor,rowColor3) EQ 0>

                    <cfset rowColor2 = 'A8E4FF'/>

                <cfelse>

                    <cfset rowColor2 = 'CECE9E'/>

                </cfif>

            </cfif>

          </cfif>

          <cfset Rowcolor = Rowcolor2/>

           <cfset Prevcolor = Rowcolor2/>

         <cfoutput group="#lstSQLOrderBy[2]#">       

              <cfoutput group="#lstSQLOrderBy[3]#">

            <cfoutput group="#lstSQLOrderBy[4]#">    

               <cfoutput>
