Undefined variables!

Folks,

How come my flash movie displays variables imported in via load variables in a dynamic text field but if I try and trace this it is coming up as undefined?

The text boxes are there as a test, basically when the variables are loaded the calender should go to frame 18.

Any help as always, apreciated.
