    if (isAdminLevel ( thePlayer ) == 3) then 
        if (intids[tonumber(int)]) and (tonumber(int) >= 1) then 
            if (tonumber(preis) >= 5000) and (tonumber(preis) <= 10000000) then 
                x,y,z = getElementPosition(thePlayer) 
                owner = "none" 
            local erg = mysql_query(sqlcon, "INSERT INTO house_data (`Int`, Owner, Preis, X, Y, Z, `Lock`)  
VALUES ('"..tonumber(int).."','"..owner.."','"..tonumber(preis).."','"..x.."','"..y.."','"..z.."','0')") 
                Housspawn() 
                outputChatBox("House created!")

outputChatBox("Invalid interior!", thePlayer,255,0,0)

Try this:

function createhouse(thePlayer, cmd, int, preis) 
    if (isAdminLevel ( thePlayer ) == 3) then 
        if (intids[tonumber(int)]) and (tonumber(int) >= 1) then 
            if (tonumber(preis) >= 5000) and (tonumber(preis) <= 10000000) then 
                x,y,z = getElementPosition(thePlayer) 
                owner = "none" 
            local erg = mysql_query(sqlcon, "INSERT INTO house_data (`Int`, Owner, Preis, X, Y, Z, `Lock`) VALUES ('"..tonumber(int).."','"..owner.."','"..tonumber(preis).."','"..x.."','"..y.."','"..z.."','0')") 
                Housspawn() 
                outputChatBox("House created!") 
            else 
                           outputChatBox("Invalid price!", thePlayer,255,0,0) 
            end 
else    
outputChatBox("Invalid interior!", thePlayer,255,0,0) 
    end 
else 
    outputChatBox("You are not authorized!", thePlayer, 255,0,0) 
end 
end 
addCommandHandler("addhouse", createhouse)
