I am looking of a long term relationship with a multi talented company. I must be provided with various ways of contact. I have had to much issues with people disapearing between projects, cant be found for new ones and i am left trying to find someone and start over. Issue 1: [login to view URL] Drop down menu not working Issue 2: [login to view URL] Product page not updating. Works great when adds to cart. See how the prices should update and total: [login to view URL] Extensions vqmods that you will need to work with: OPA Options Boost Issue 3: This extension seems to have stopped working now: [login to view URL] Option prices should be showing in cart: [login to view URL] I had someone working on this and then they just disapeared in the middle of fixing the site and create more problems for me to fix.
