Invalid column name for the group attribute.

Question

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>
</cfoutput>
</cfoutput>
                    </cfoutput>
                </cfoutput>
            </cfoutput>
        </cfoutput>

Answer 1

These tags are somewhat ambiguous, as they have no query attribute:
<cfoutput group="#lstSQLOrderBy[2]#"> 
<cfoutput group="#lstSQLOrderBy[3]#">
<cfoutput group="#lstSQLOrderBy[4]#">
