Try the suggestion below and see how the generated *.py code does it.

In this case:
the radio button id should be my_usrp_freq
the radio button choices should be [900e6, 950e6]
The radio button labels should be ['Yes', 'No']

Enter the id of the radio button, my_usrp_freq, into the usrp frequency 
parameter.

Then, execute the flow graph. It will work. :-)
