ActionScript 2.0 :: Loading Vars - Adding Values To Graph?

I have a flash file which loads in vars from director. It then adds the values to a graph. The amounts from the string are inputed into text fields. the fields are named energy, waste etc. I want a textfield to output whichever sections that are over 5 saying "well done, you have excelled in water, energy...... I have got this working but am stuck on this bit: I am wanting to add an "and" before the last item, so it outputs as "well done you have excelled in water, waste and energy". Also if only one item is over 5 it wont add the "and". This probably doesnt make any sense, heres my code anyhow:

Code:
var summary_results = "2000,6,3,10,8,6";
var txtFields:Array = [Total,Energy,Waste,Water,Food,Transport];
var excelledItems:Array = [];
var theValues:Array = summary_results.split(",");
for(var i=1;i<theValues.length;i++){
[Code] .....
