Express Work Order button personalization

A client of mine is asking for the ability to create an express work order from the asset details screen, similar to the Create Work Order/Create Work Request functionality.

I didn't want to get in to a customization and play with the View LOV, so I tried adding a button to the screen.

I was able to add the button and get the Express Work Order page to launch but it is not populating the asset number (as the Create Work Order does). The URL that opens the Express Work Order shows the Instance Id being passed.

I have attached screen shots showing my work. Client is on 12.2.5.
