try/catch to see if the index exists in the array. Keep in mind that in
CF, once a variable exists, it always has a value. Maybe you are
thinking abaout empty strings when you say "no value" (although empty
strings are a value). Then right after testing if the array index
exists, check for the Len() IF it exists. You could make it into a
function (look at http://www.cflib.org/udf.cfm/ArrayDefinedAt).
