> [@Darren\_Murphy](#): > > Custom Form Just one more Q. Can you clarify the term “custom form”? @Jeff_Hager states it is > [@Multi-step form](https://community.glideapps.com/t/multi-step-form/34556/4): > > just a detail screen When I make changes to a Detail Screen it is made for every use of that screen (per Table) unless I am using “Independent screen configuration per item”, which has a very specific purpose that I don’t need. So I’m guessing that @Jeff_Hager is saying it is Detail Layout. Yes, I could customise Edit or Detail or Add but they would be changed in every use of those native forms. I suppose that what I want to use is Show New Screen action or Show Form Screen action to create my custom form. I use New if I want to look at the same data that was on the screen with the action and I use Form if I want to start from scratch without any context. I am trying to create a custom Delete button on an Edit screen. Delete action has many, reasonably complex options. I lost all my work when I changed the action screen type but when I start again I will use a Show New Screen action and then build from there. I will be careful never to change the action type. Is that a reasonable understanding? --- _[View the full topic](https://community.glideapps.com/t/when-does-glide-do-math-column-recalc/55693)._
