I cant find the output of my script on the screen, executor i can see in task bar but nothing is coming out of output on the screen

As per your code - it should display a message box first. After clicking ok on the message box - It should display a window to enter a value

Then after entering - it should display the entered value

Let us know if at least the message box is coming or not?

Also the input window / message box might be displayed anywhere on the screen in desktop. try minimizing studio browsers etc. to see if it is coming in the background
