Hi Rob
I don't believe using StringValue will make any difference. If you're passing a string, it should amount to the same thing.
Some things to try:
Try setting the value using the SetValue QPAC - does that work?
Try testing your form by setting an XML file containing "Fl" in the state field as your preview data (In Designer, File/Form Properties)
Try using the Variable Logger to check the data in your form is set correctly.

Good luck...
