Adding a new sidebox

Im currently trying to add a new sidebox. I would like it to display the "Add selected products to cart" as seen here:

Ive gone through this tutorial

http://www.zen-cart.com/wiki/index.php/Tutorial

I was hoping you could help how I could actually add to the content to display the add selected products to cart button?

Try this one it even puts a pic of the product in the side box I tried it yesterday and it is ok even though it's rather old http://www.zen-cart.com/downloads.php?do=file&id=553 in fact it's almost identical apart from the addition of the image.

think this is the one they are using Shopping cart sidebox with checkout button http://www.zen-cart.com/downloads.php?do=file&id=824

I have had that already, its not a checkout button I need in a sidebox, I need an "add selected products to cart" in the sidebox. I don't think there's a plugin for that so Im trying to make my own sidebox.

Its really hard!

Haha, I think I should explain myself a little better.

https://www.Kitchenwarehouseltd.com is my website, Im trying to add the button "add selected products to cart" into a new sidebox, so im trying to make my own sidebox.

This is going to be tough, because I believe the "add selected" button needs to be inside the form where the selections are made, while any sidebox will be created entirely outside of the center column and the form. There may be an answer, but it will take an expert in this aspect to find it.

Perhaps the add selected code can exist within the form code, but be displayed in a sidebox location.
