Checking quantity of dropdown menu

[threers]

I am using 1.3.9h and am having trouble with quanties of attributes. Let say I am selling t-shirts in different sizes. I have 10 small and 5 medium and 7 large and 8 extra large. How do I set the system to check those quantities and not let the customer put in cart if they order 6 medium and get those qty to display for customers as well.
