Shortcut for dollar sign (interpolation)?


Could someone help me how can I type sign (interpolation) as a shortcut? I used sign from my keyboard but I think it keeps showing wrong in my code. Please see the photo. It happened in the previous codes too. Is it because of Interpolation $ or something else ?

. Thanks

sorry, my real question is where I am wrong as I checked with the solution and everything is same but the code is not moving forward? thanks

It’s not quite quote marks, it’s the backtick button `.


Thank you , found the way.
