It would be more helpful if you could just explain correctly what you're looking for. I would say it looks like chinese but your code is literally that.
fysiks already gave u the answer more or less on the "question" u asked.
PHP Code:
if(g_skills[id] < 0)
{
g_skills[id] = 0;
// client_printc()
}
else if (g_skills[id] < 100)
{
// click skill & close menu?
}
