I am completely newbie (completely). I asked the question [here](https://stackoverflow.com/questions/64726432/how-to-write-on-other-values-placed-after-the-operators-case), I received no answer. Here I did not upload the whole project to the link, I think it is clear what kind of help I am asking.  
Good afternoon, I’m using the switch construct, but I don’t know how to write correctly for other values after case statements.  
Only works at (minutesss = cp5.addButton) - 10, (Vin = cp5.addTextlabel) - 60.

The main error is below (function “setText (String)” is undefined. See screenshot.

How do I fix this for variables and write it correctly?

ImageButton;

Numberbox inputPULI;

Numberbox inputNapryzenieKV;

RadioButton CheckBoxuvum;

CheckBox P4;

See the GUI file!

A task:

ImageButton (button) - 20, the goal is to get a change of the picture in the window.

P4 = cp5.addCheckBox - 30 CHECK, the goal is to enable and disable changing the state of the checkbox in the window.

inputPULI = cp5.addNumberbox - 40 Bullet, the goal is to get an integer change in the window.

CheckBoxuvum = cp5.addRadioButton - 50 +/-, the goal is to enable and disable (+/-) the state of the checkbox in the window.

inputNapryzenieKV = cp5.addNumberbox - 70 Voltage, the goal is to get the change of the floating point number in the window.

In the Displaydata code, I marked this with a question.

In the future, I plan to send commands from the terminal via the com port to receive a change in the data state in the window for these values.

Screenshot of errors:

</div>

I asked a question [https://stackoverflow.com/questions/64726432/how-to-write-on-other-values-placed-after-the-operators-case](https://stackoverflow.com/questions/64726432/how-to-write-on-other-values-placed-after-the-operators-case) here, got no answer. Correct everything and write for the numbers (DisplayData fix) 20,30,40,50,70. I myself don’t know how to ask (((I know the working code. Maybe I can upload the project here in full files so you can see?)

I can’t help you with that

basically here you have to evaluate all your controls and act:

**See processing, menu file, examples, contributed libraries, controlP5…**

```auto
if (theEvent.isFrom(CheckBoxuvum)) {
     //myColorBackground = 0;
} else if(theEvent.isFrom(........)) {
    // 
} ................
.........

```
