Are you sure?
It looks to me like sortSetting might be '0' - a string - and
so neither of the two clauses in the function get called and it
therefore returns the default value of None....

Just a guess though... Try running it in the debugger and steping
through the code with a watch on sortSetting to check its value
(and type!). This is the kind of problem debuggers are designed
for :-)
