So if you put a break point immediately after
setax = setA.split(" ")
then setax is nil, but if you then (while still broken) do
setax=setA.split(" ") then setax gets a value.
If so I find that most remarkable.

You have not said how setax and setbx are defined. Are they db cols
for the model in which setup_data is defined or what?
