[Discuss-gnuradio] Variable Delay Error

[António Gomes]

Hi all,

I'm trying to make a delay on a signal with a variable delay with a WX GUI Slider. When i run the simulation and try to add a delay on a sinusoidal signal it gives me this error:

linux; GNU C++ version 4.7.3; Boost_104900; UHD_003.005.003-163-gfeabc1c7

Using Volk machine: avx_64_mmx_orc

Form: <class 'gnuradio.wxgui.forms.forms.text_box'> ->  Error translating value: "200.0"

in method 'baz_delay_sptr_set_delay', argument 2 of type 'int'

Enter a float with optional scale suffix.  E.g., 100.1M

I don't know how to correct it or what i'm doing wrong. Can you help me?

You can see on the picture below my block diagram.

Kindest Regards,
