"MSGBOX" doesn't work any more.

[Mackeral]

On my computer, "MSGBOX" has stopped working.

If I call it with one argument, it works correctly.

However, when I call it with 2 arguments it gives an error message. And that should work according to the instructions I find on the Internet.

What does your code look like, and what is the error message being displayed?

 

[Mackeral]

In the documentation as I read it implies that the arguments are optional.
But in fact they are NOT optional: the second argument, for instance, has to be a number corresponding to one of the "Msgbox Arguments".
The third argument is a string to be used as the Msgbox title.
And so on as per the Msgbox documentation

It does not 'imply' that at all. It expressly states what is required and what is optional.
I don't know what "the MsgBox documenation" is that you're referring to, but here is the actual documenation: MsgBox function (Visual Basic for Applications)

The first argument - prompt - is required.
The second argument - buttons - is optional. It even states that "If omitted, the default value for buttons is 0."

Given that statement, the other arguments clearly are optional. (I've unmarked your answer by the way as it is not correct)

You haven't really provided any information, but I would guess that you either tried to enclose multiple arguments in brackets without storing the result, or you passed them in the wrong order without using named arguments.
