Link to the challenge:

You should declare myName with the var keyword, ending with a semicolon

I did that, can you show me an example please?

Your code has the following line

var myName = "Mercy" 

Note that there is no semicolon at the end.

You can check the second screen shot

Ah I see, you should not give myName a value.

I don’t understand you,
What am I supposed to do?
Please give me an example here. Am still stuck
