Why “Empty do” error when my do isn't empty?

Question

I am trying to create a menu which gives output based on user input. However, I get a empty do error even though I have code for it to do underneath it. Am I missing something?<

Answer 1

The statements in a do block must be indented further than the start of the line containing the do. But you have other problems too, like using a let, which does not make sense here.
