question for WinCC comfort panel

hi guys

I just got a question for the WinCC Comfort Panel:

I design a button with function to go to another screen, the function was runing ok when I simulated it, but when a download to HMI, the function did not work. anybody could help me figure it out?

thanks

Can you give some more detail?
So this is just a button press or release that runs a go to screen?
Not a script right?
