[Discuss-gnuradio] random number coding problem

[김무연]

Hi all

I was trying to make a block 

which acts if input is 1,then output is random number and if input is 0, then output is the same previous time

So last time I asked what should I use instead of rand()

I tried to program as you told

But I think there is something I didn't understand

I post a picture of my screen

So could you give me some advices?

Thanks
