--Counting Bowl    by MrStump

--Table of items which can be counted in this Bowl
--Each entry has 2 things to enter
    --a name (what is in the name field of that object)
    --a value (how much it is worth)
--A number in the items description will override the number entry in this table

    [""] = 1,
    --["Name3"] = 2,
    --["Name4"] = 31,
    --Add more entries as needed
    --Remove the -- from before a line for the script to use it
