Send data from Nextion to Arduino


I am working on a project where I have to get data from the display and assign the values to some variables in the Arduino Code. Currently, I have only programmed one button. I am using the basic 2.8 inch nextion display.

On the Homescreen, the user can see 3 textfields. On pressing any of the textfields, the user is taken to another screen where they can input the value they want. When OK button is pressed on the input screen (Keypad), I want the Nextion to send the data to the Arduino. I use a variable in the Keypad screen to know which field was pressed so that only that variable's value can be updated in the arduino code.

Any help would be greatly appreciated. I have no knowledge of how the nextion library works since I am a newbie.
