ERROR : Not enough input arguments

[CJ Vaughn]

Hi Antonino,

Can you share the line of code which calls the function startupFcn?

[Antonino Marino]

app.ruolo = arg

Hi Antonino,

Based on the comments in the provided code, it looks like you are using App Designer.

When designing an application using App Designer, it is possible to specify input arguments needed to run the application. The following line indicates that there is one input argument (arg) for this application.

function startupFcn(app, arg)

To enter input arguments, expand the drop-down list from the Run button in the toolstrip. In the second menu item, specify comma-separated values for each input argument. The app runs after you enter the values and press Enter.

For more information on creating and working with input arguments, please see the documentation here:

yes, but how many arguments do I have to put?

[CJ Vaughn]

This application has one argument.

How many arguments does your app need? Supply everything that is needed to run it, whether that is 1 or 2 or 5 or whatever. We don't know but you should.

where can i see how many arguments my app requires?
