Try
self.yspeed.get()
to get the value of the variable.

David,
Appearantly, you're refering to self.yspeed to get the value of the
variable, although you seem to have initialized self.yspeed with an
instance of Tkinter.StringVar or one of it's friends.
To get the value, use self.yspeed.get(); the object itself is simply
a reference to a Tcl variable. The get() method will return the value
as the data type indicated by the name of the class you instantiated
to create self.yspeed.
