product size and colour problem

[media101]

hello all, PLEASE HELP!!
i have gone crazy looking for a solution... this is my problem; i have a clothing website and i am unable to put in a size and colour. so when a customer wants to buy a t-shirt size large colour red, the customer can pick that and then once its added to the cart it will remove that item from the list of t-shirts that are there.

so lets say i have one size small and one size large, once the large is bought the only size available left is small.

also im very new to joomla and virtuemart so i need a step by step guide and iv no code knowledge.

super thanks to anyone who can help me out
