Argument '<argumentname>' must be within the range 1 to 255

An argument is not valid because it falls outside of the range 0 to 255.

To correct this error

  1. Check the spelling of arguments in the expression. A misspelled variable name can implicitly create a numeric variable that is initialized to zero.

  2. Check previous operations on variables in the expression, especially those passed into the procedure as arguments from other procedures.
