hi guys,
since 2 days i've not been to resolve this, your help will save me further days of torture.
The below code shows the cart of a customer’s session: it shows each product, quantity and price and then save’s it to a session. It all works fine.
The first problem starts when the product is a shoe. So if the product is a shoe I allow them to enter the shoe size, next to the quantity. I tried many using a foreach loop within another, but that’s just not working.
The second problem is saving the shoe size for each product the session too.

It's hard this way, not seeing the complete code, I made some wrong assumptions.
