Plz help to solve the problem

I tried the tictoc example in Omnet++ IDE according to the tutorial and face problem to configure initialization file.

Firstly, I just copy the following code:

[Config Tictoc4]
network = Tictoc4
Tictoc4.toc.limit = 5

[Config Tictoc5]
network = Tictoc5
**.limit = 5

And got the above two errors and two warning. So, I modified the code like the followings:

[Config Tictoc4]
network = demo1.TicToc1
Tictoc4.toc.limit = 5

[Config Tictoc5]
network = demo1.TicToc1
**.limit = 5

Now, the two errors are gone but there are two warnings like the following:


I am really very anxious about the errors and I am a beginner to work in Omnet++ . So, if anybody can tell me the solutions then please tell me in the comment section. This definitely help me if you tell me the way to solve the problem.

Thanking you....
