repeat until ValidInput = true
That means: "I'm going to keep asking the user for valid input." More experience in scripts will show you that you use this trick often: "Repeat forever until I get valid input."
Usually you'll just see "repeat until ValidInput"
It's the return statement that ends the otherwise endless loop. And, as a comment, I find that code misleading because it implies that that test will actually be used to exit the loop, but it isn’t. I recommend changing it to just “repeat … end repeat”, which makes it clearer to the reader that the loop is exited due to some code inside the loop.
Also, I prefer to put whitespace around (above and below) return statements so that changes in flow control stand out:
if (NoRange > 2) and (NoRange < 60) then set NoRange to NoRange as integer --Convert the player input --Question: Why do I need this step???? A: see page 101 “Coercion”
return NoRange -- Return the player's input
else -- Display an error message if the input is not valid
