Help with script menu

after executing a script menu i purchased i am presented with the following options on my scroll menu

change weapon
[Select Mod]
Dayz
Dayz epoch/overpoch


i scroll down to dayz epoch/overpoch and press the key to activate it, however nothing happens
I can change my weapon, open doors, etc. using the scroll menu, but i am unable to do anything with the script
this is the case for other scripts which i have tried, can somebody help

Try to choose something else, like if you tried to choose DayZ Epoch/Overpoch try to choose DayZ or Overwatch.

tried that, didnt work
