Hi,

var is a javascript keyword that you are using to declare a variable.
Here with the help of var you have declare two variable a and b.
And you have successfully assign a value of 7 to variable a. Now you have to assign the variable a to the b. Remember we have to declare variable only once with the same name.
I hope you can catch the error now.

thank you. I don’t understand very well though. Did I not assign the value of a to b here: var b = var a;?

And from what I can see the vars have only been declared once: var a; and var b; ?

By using var b = var a, you are declaring the variable a and b again. I hope you can catch the error this time. Read the problem statement and my explanation carefully. Its very simple error.
