RPT Issue Reported:

19:10:01 Error in expression <ter == "pammunition" && !(player canAdd _newItem) || currentWeapon player != "")>
19:10:01   Error position: <_newItem) || currentWeapon player != "")>
19:10:01   Error Undefined variable in expression: _newitem


    So since it is undefined variable expression, we have to assume that somehow _newItem is being set to NIL
    So how to fix this? We handle it.
    We make sure the data we are using is validated.
    How do we validate data? If statements galore.
    Watch and learn boi, look for the //validate comments

    Okay also for safe practice we should declare our variables first as empty/default
    look for the //declare comments
