ViewON display system informations with Getsys

Hi,
My client, want to display the Wifi name on ViewOn, but he has juste ‘?’
He program script like this, can you tell what is the problem?

Hello,

I believe you need this statement before you do a getsys.

Setsys COM, “LOAD”, "WifiSSID"
wifi_name$ = GETSYS COM, “WifiSSID”
