    while Amount > 0 and islocation(1) do

        buyitems(getuseroption("HealthName"), Amount)

         Amount =  Amount - 100 --and this one

        wait(250,500)

    end





    local Amount = (MpCount)

    while Amount > 0 and islocation(1) do

Need more information, what are you trying to do/understand?

edit: ahh i see the areas now that it has lua tags!

the first one removes the itemcount of smp from the variable MP and stores it in the variable MpCount
the second one removes 100 from the variable Amount
