OutofTree Block C++ problem

Good afternoon,

I am working on making my own source block. I am trying to use the 

gr::random::random in my C++ QA code but it does not seem to work. Here is the error message:

error: cannot convert 'gr::random' to 'double' in initialization

61|    double X = gr::random(0,0,2)

    |                           ^~~~~~~~~~~

    |                           gr::random

I'm not sure what I am doing wrong. Can someone explain to me why I am getting this error? Am I not calling it correctly? Please and Thank you for your help. I am on Ubuntu 20.04 and using Gnu Radio 3.8.4.0. Here is the code for reference:
