Thnx for all the suggestions...Now i have made amendments to my program and
its working now...but there is a new problem now....I am now calling a
python script generated by GNU Radio Companion(for those who know about GRC
will understand my question better)...when i press the execute button i get
the following error..Both files are as attached.Is there a different way to
call a script generated by GRC??
Form: <class 'gnuradio.wxgui.forms.forms.text_box'> -> Error translating
value: "<__main__.MyFrame; proxy of <Swig Object of type 'wxFrame *' at
0x30f44a0> >"
bad operand type for abs(): 'MyFrame'
Enter a float with optional scale suffix. E.g., 100.1M
Form: <class 'gnuradio.wxgui.forms.forms.slider'> -> Error translating
value: "<__main__.MyFrame; proxy of <Swig Object of type 'wxFrame *' at
0x30f44a0> >"
unsupported operand type(s) for -: 'MyFrame' and 'float'
Value should be within slider range
