@Tim Pilgrim you can’t deploy a user event or client script to the inventory Detail through a script record. But you can add a client script directly to the inventory detail form. If you need to get information from the item receipt record from the client script on the inventory detail, the only way to do that is to access the parameters in the url. There’s quite a few parameters in the inventory detail url that carry a lot of information about the item receipt record, but you can’t see them sine the inventory detail is a pop up. If you need a code sample for how to access that I’d be happy to send that over to you. I’m not sure if you would consider that a browser hack, but that’s the only way to access that information.
