Not enough input arguments error

I'm new to Matlab and following a beginner textbook, and I get the following error message for this simple code:

Not enough input arguments.

Error in price (line 3)

= items*130

function price(items) 
  % If Construct example
  price = items*130
     if items > 5
     price = items*160
end

Thanks in advance

Most likely that is due to your using the green Run option in the Editor rather than calling your function from a script, as it was designed for (in this instance).

If a function has arguments (not all do), you need to provide those arguments. This is most easily (and reliably) done by calling it from a script.
