Just started the Inter Process Communication Course and whenever I am running my own code it returns : : within the console. I have run the code that is already in the developer and it works but when I run my own code it only displays : : . I have run all the previous code on the render markdown that I am able to.

Hi Joe,

Would you be able to provide me with a few extra details about this.

- Are you running your code in the markdown file or the scratchpad?

- Have you experiencing this issue with the content file or the exercises file or both ?

- Can you send a screenshot of an example of this happening?

Many thanks,

Megan

Hi Joe,

Can you send an example of a code snippet you are trying to run in the rendered markdown file that causes this problem ? Such as this:

I may have to access your server to get a closer look.

Many thanks,

Hi Joe,

So ' : : ' is the generic null value in Q. If a function returns no value it actually returns ' : : ' .

Take a look at the example below, when this function is passed a parameter of 4, it returns 4.

But if we don't pass it anything, it returns null.

Hope this helps!

Thanks,

Megan
