This is not the same issue as the problem you initiated this thread for. Please start a new thread for new problems.
There are a number of problems I see in your page:
1) each different item should have a unique ID
2) The ID's should be numeric, you are using text.
3) the Add to cart buttons should only be created after all of the cart columns have been added to the eCart object.
4) in the eCart object, set the unique attribute for columns that should seperate a product. For example, to have a separate line item created for item 1 in red and blue, the color column must have the unique attribute set.
some of your add to cart buttons do not include bindings for either the color or size column, this will only happen if the add to cart button was added to the page before the column was created. double check the unique attributes in the eCart object, then recreate the add to cart buttons on this age.
