Error: The function must have both parameters specified
Description
This error is displayed in the list of errors and warnings at the bottom of the procedure editor when the procedure uses a function that needs two parameters - i.e. values that the function acts on - but one or both of these parameters has not been specified.
This applies to the following functions:
| • | Pow function, to return a number to the power of another number |
| • | Random function, to generate a random number between two values |
| • | Round function, to round a number to a given number of decimal places |
The missing parameter will show as '...' in the procedure editor; you need to type in a relevant value or drag an expression into the place of the missing item.
More information
Everything in an ANY-maze procedure that accepts a parameter (i.e. the thing or things that it operates on) must have all parameters specified. You can't leave any empty 'holes' in any statements of a procedure.
