Inventory:Get(xxxx) only returns a single item (inventory slot). Inventory("itemid=xxxx") returns a table with however many stacks it found.
You'll need to add them up yourself.

Does that help?

Code:

local inv= Inventory("itemid="..fishID)
    if (inv) then
        for k,item in pairs(inv) do
            d("------------"..item.name..": "..item.count)
        end
    end

how did you get the GUI field to size correctly?
