Different Sizes options
I am struggling a little with my first ecart site and cannot seem to find a suitable resolution on the similar forum posts I have read. The site I have is a static one, using php and I am dealing with add to cart coding on the product pages only
I have some products which have 2 size options, and each size has a different price. For ease of reference, let’s say option 1 is £5 and option 2 is £10
I have managed to set up my add to cart on the product page and coded the option list to reflect the price/size differences. These are carried over to the cart successfully on a single purchase, however, if then the other option is chosen and added to the cart, I end up with 2 of the same item at the originally chosen price.
In other words, if I choose option 1 at £5, then return to the product page to buy option 2 as well, option 2 is added to the cart as 2 x option 1 at a total purchase price £10. The situation is reversed if option 2 is chosen first.
From reading other posts I believe this is to do with the add to cart coding/bindings, but I struggle to follow the instructions as the scenarios are different to mine.
Would it be possible to guide me through the process step by step so that I can understand what should be happening and where I am going wrong here?
Please bear in mind that I am a novice.
