Fix minor issues with Virtuemart custom field plugins

Hi, I had a developer work on some plugins for my Virtuemart shop. The shop i Tailored Suits webshop where people can buy suits. The are two types of product pages, 1. ordinary products 2. Custom suit For the custom suit page the must be 5 steps where the customer choose customizations and accessories. Step 1. "Jacket" - here the customer chooses different customization options Step 2. "Pants" - here the customer chooses different customization options Step 3. "Accessories" - (extra products) Step 4. "Measurements" - here the customer inputs his measurements. Step 5. Checkout I already have the plugins for the customizations and the measurements but they need to be corrected and I need to make the product page work with the 5-step process. Here you can see the "Custom suit" page: [login to view URL] As you can see there are som issues with the plugins and the 5-step has not been made yet. The 5-step process needs to work similar to this page: [login to view URL]
