Lua doPlayerRemoveMoney problem

[BeniS]

I'm having problems with the doPlayerRemoveMoney function in 0.3.6pl1, its returning a false value even though the player has money on him. The transcript example is below:

Transcript:

12:18 GM Maverick [331]: hi
12:18 Naji [Bank]: Welcome to the Tibian bank, GM Maverick! What can I do for you?
12:18 GM Maverick [331]: deposit all
12:18 Naji [Bank]: Would you really like to deposit your all money, 10000 gold coins?
12:19 GM Maverick [331]: yes
12:19 Naji [Bank]: You don't have 10000 gold coins.

Code (Deposit):

    --deposit
    if talk_state[cid] == 20 and getCount(msg) > 0 then
        talk_state[cid] = 21
        last_count[cid] = getCount(msg)
        sayText = 'Would you really like to deposit ' .. last_count[cid] .. ' gold coins?'
    elseif talk_state[cid] == 20 and msgcontains(msg, 'all') then
        if getPlayerMoney(cid) <= 0 then
            talk_state[cid] = 0
            sayText = 'You don\'t have any money.'
        else
            talk_state[cid] = 21
            last_count[cid] = getPlayerMoney(cid)
            sayText = 'Would you really like to deposit your all money, ' .. last_count[cid] .. ' gold coins?'
        end
    elseif talk_state[cid] == 21 and getCount(msg) <= 0 then
        if msgcontains(msg, 'yes') then
		 local balance = getPlayerBalance(cid)
            if doPlayerRemoveMoney(cid,last_count[cid]) then --This is the problem line
			    setPlayerStorageValue(cid, 50505, balance+last_count[cid])
                sayText = 'You deposited ' .. last_count[cid] .. ' gold coins. Now your account balance is ' .. getPlayerBalance(cid) .. ' gold coins.'
            else
                sayText = 'You don\'t have ' .. last_count[cid] .. ' gold coins.'
            end
        else
            sayText = 'Well, can I help you with something else?'
        end
        talk_state[cid] = 0
    end

Hope someone can help me out, this problem is annoying me now
