Hey,
Sorry to hear you're having trouble getting the script up and running. Please could you open the console logger (via the settings gear at the top right of the OSBot client), and then try starting the script? The script will immediately stop if there is a configuration issue or if it is otherwise unable to continue, and the reason for stopping is always displayed in the console logger, so this should hopefully help you determine the issue.
If I was to hazard a guess at what might be the problem, perhaps you have enabled ammo looting without the game configuration for auto-equip being set? If this is the case, it should display a warning message when you start the script; this warning should direct you to speak to the lumbridge guide to enable this feature.
Please keep me updated with how you get on
Apa
