end

function onCreatureSay(cid, type, msg)
  	msg = string.lower(msg)
end
if (msgcontains(msg, 'hi') and focus == 0) and getDistanceToCreature(cid) < 4 then
selfSay('Yooooo ' .. getCreatureName(cid) .. ', waddup man?')
focus = cid
talk_start = os.clock()

        end
        focus = 0
        talk_start = 0
    end
    if focus ~= 0 then

Use TFS bootsmaker.lua(?) as a base (The one that refills soft boots for you).
