Or better yet here's an (untested) example: <cfset foundArray = arrayNew(1)> <cfloop list="#form.fieldNames#" index="x"> <cfset wasFound = false /> <cfloop from="1" to="#arrayLen(foundArray)#" index="y"> <cfif foundArray[y] EQ form[x]> <cfset wasFound = true /> </cfif> </cfloop> <cfif wasFound> <!--- logic to handle a duplicate found ---> <cfelse> <cfset ArrayAppend(foundArray,form[x])> </cfif> </cfloop>
