[HELP] Compare boolean with number

[..:D&G:..]

Hello, I made this set wanted level function but I keep getting the error "Attempt to compare boolean with number".

function setPlayerWanted(thePlayer, cmd, who, amountWanted) 
    if isPlayerOwner(thePlayer) or isPlayerSuperMod(thePlayer) then  
        if not (who) then 
            outputChatBox("SYNTAXA: /"..cmd.." [Name] [Wanted]", thePlayer, 255, 255, 0) 
        else 
            local amountWanted = tonumber(amountWanted) 
            local player = exports["(wG)Tools"]:findPlayer(who) 
            if not amountWanted < 7 and not amountWanted > -1 then 
                return 
            else 
                setElementData(who, "wantedPoints", amountWanted) 
            end 
        end 
    end 
end 
addCommandHandler("setwanted", setPlayerWanted) 

Here is the error:

if not amountWanted < 7 and not amountWanted > -1 then 

Even though I put a number when I type the command, and when I've defined "amountWanted" as a tonumber, it still reads it as a boolean... Any ideas what's wrong?

if not amountWanted < 7 and not amountWanted > -1 then

not amountWanted - return boolean

if not ( amountWanted < 7 ) and not ( amountWanted > -1 ) then

It worked, thanks
