A previous administrator add a bunch fields for each product on the first page of the opportunity form. They enter onload and onsave events to fill in the Est. Revenue total field by adding up these other fields they added. Now, when I go to products and click on the add products button nothing happens. I have checked the attributes and the one for the opportunity product does exist and I have removed the onload and save events and code for the onchange event of the est. revenue total field and still can't get the button to work. What am I missing?
Going forward we want to use the crm built in reports and functionality for this so I need to get it back factory :).
