Form total wrong and options wrong when passed into PayPal

Hi,

I've created a form which works fine until I pass it across into PayPal. The form has different prices for different quantities so I set up a product dropdown menu for each price and the fixed quantities (20, 30, 40, etc.). There are 3 additional extras which can be added, I tried to do these as an option with 3 checkboxes but the total didn't work so I used 3 separate product fields with 'Yes/No' radio buttons for the extra to be added. Each one opened an hidden quantity field associated with it when clicked on 'Yes'. This obviously created lots of quantity fields in the admin but they worked OK until the form was submitted to PayPal which won't display the additional extra with it's associated quantity. Can anyone help me with this?

Form is here: http://www.myweddingteatowels.co.uk/ordering/order-tea-towels/

Thanks.

Thanks for you reply. I've removed the PayPal sandbox so you should be able to see a total go over now.

The total for the main product is correct but I hard coded those into a product dropdown which looks like a quantity dropdown to the user with different prices for each quantity. It's the options which only pass over as one rather than the total. When I used an option field with 3 checkboxes, it didn't update the total at the bottom of the form for some reason?

Thanks for your reply. I ordered 20 from the dropdown which came to £73 and then added an extra for £0.15 which came to £76, as it should. When I pass this to PayPal it drops to £73.15 as it only adds one of the extras. Do you know why it's doing this?

The dropdown menu is actually a product list and quantity fields appear using conditional logic and it's these that act on the additional options. It seems that PayPal doesn't recognise these hidden quantity fields.

I've just hidden the quantity fields using CSS and this works fine.

Yes it is, thanks.
