[soul4soul]

here is the script

function onSay(cid, words, param)	
--Start configuration --
	local items = 
	{
	 ['hp'] = {cost = 45, storage = 49989},
	 ['shp'] = {cost = 100, storage = 49988},
	 ['ghp'] = {cost = 190, storage = 49987},
	 ['uhp'] = {cost = 310, storage = 49986},
	 ['mp'] = {cost = 50, storage = 49985},
	 ['smp'] = {cost = 80, storage = 49984},
	 ['gmp'] = {cost = 120, storage = 49983}, 
	 ['gsp'] = {cost = 190, storage = 49982}
	}	
-- End configuration --	

	local t = string.explode(param, ",")
	local item = t[1]
	local amount = tonumber(t[2])	
	
	-- Checks if we can use that itemname --
	if item then
		-- Checks if the player has enough money --
		if doPlayerRemoveMoney(cid, item.cost*amount) == 1 then
			doPlayerSendTextMessage(cid, 24, 'You have bought '..amount..' '..item..' charges for '..(item.cost*amount)..' golden pieces.')
			setPlayerStorageValue(cid, potion.storage, getPlayerStorageValue(cid, potion.storage)+amount)
		else
			doPlayerSendCancel(cid, 'You dont have enough money to buy that many charges.')
			doSendMagicEffect(getPlayerPosition (cid), CONST_ME_POFF)	
		end
	else			
		-- Sends the player a message wich includes items he can buy --
		doPlayerSendTextMessage (cid, 24, 'You can buy the following items:')
		-- Getting the all itemnames --
		for item1 in pairs (items) do	
			-- Sends a message with each itemname and price --
			doPlayerSendTextMessage (cid, 24, item1)
		end
	end
end

<talkaction words="!charges" event="script" value="charges.lua"/>

Try this. Rep++ if works.

function onSay(cid, words, param)	
--Start configuration --
	local items = 
	{
	 ['hp'] = {cost = 45, storage = 49989},
	 ['shp'] = {cost = 100, storage = 49988},

	 ['smp'] = {cost = 80, storage = 49984},
	 ['gmp'] = {cost = 120, storage = 49983}, 
	 ['gsp'] = {cost = 190, storage = 49982}
	}	
-- End configuration --	

	local t = string.explode(param, ",")
	local item = items[t[1]]
	local amount = tonumber(t[2])	
	
	-- Checks if we can use that itemname --
	if item then
		-- Checks if the player has enough money --
		if doPlayerRemoveMoney(cid, item.cost*amount) == 1 then
			doPlayerSendTextMessage(cid, 24, 'You have bought '..amount..' '..item..' charges for '..(item.cost*amount)..' golden pieces.')
			setPlayerStorageValue(cid, potion.storage, getPlayerStorageValue(cid, potion.storage)+amount)
		else
			doPlayerSendCancel(cid, 'You dont have enough money to buy that many charges.')
			doSendMagicEffect(getPlayerPosition (cid), CONST_ME_POFF)	
		end
	else			
		-- Sends the player a message wich includes items he can buy --

try using doPlayerRemoveItem?

 

[soul4soul]

i tried changing

if doPlayerRemoveMoney(cid, item.cost*amount) == 1 then

to

if doPlayerRemoveMoney(cid, item.cost*amount) == LUA_NO_ERROR then

but it didnt help.... i said !charges mp,100 and i lost 50k but didnt get any type of message and i didnt poof

 

[soul4soul]

function onSay(cid, words, param)	
--Start configuration --
	local items = 
	{
	 ['hp'] = {cost = 45, storage = 49989},
	 ['shp'] = {cost = 100, storage = 49988},
	 ['ghp'] = {cost = 190, storage = 49987},
	 ['uhp'] = {cost = 310, storage = 49986},
	 ['mp'] = {cost = 50, storage = 49985},
	 ['smp'] = {cost = 80, storage = 49984},
	 ['gmp'] = {cost = 120, storage = 49983}, 
	 ['gsp'] = {cost = 190, storage = 49982}
	}	
-- End configuration --	

	local t = string.explode(param, ",")
	local item = items[t[1]]
	local amount = tonumber(t[2])	
	
	-- Checks if we can use that itemname --
	if item then
		-- Checks if the player has enough money --
		if doPlayerRemoveMoney(cid, item.cost*amount) == LUA_NO_ERROR then
			doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, 'You have bought '..amount..' '..t[1]..' charges for '..(item.cost*amount)..' golden pieces.')
			setPlayerStorageValue(cid, item.storage, getPlayerStorageValue(cid, item.storage)+amount)
		else
			doPlayerSendCancel(cid, 'You dont have enough money to buy that many charges.')
			doSendMagicEffect(getPlayerPosition (cid), CONST_ME_POFF)	
		end
	else			
		-- Sends the player a message wich includes items he can buy --
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, 'You can buy the following items:')
		-- Getting the all itemnames --
		for item1 in pairs (items) do	
			-- Sends a message with each itemname and price --
			doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, item1)
		end
	end
	return true
end

there was a few bugs but everything seems to be fine now.
