I am attempting to basically replicate the product object and functionality for a custom object I created called 'Inventory' on the opportunity records. I have created a button called 'add inventory' to the inventory custom object on the opportunity but I am not great with APEX or Java and I need the button to bring up a multi-select list of all of the 'inventory equipment' which have been uploaded as records on another custom object called 'inventory equipment'. It is literally exactly what the add product button does but I need it to bring up all of the inventory equipment records and relate them to the opportunity.
