Add Formula Within Detail View

Seems if I’m editing a Detail View (e.g. creating a layout) I can’t add a column that’s driven by a formula.

Is there a reason for that?

Hmm you should be able to add the column. Can you give a gif example or something?

Ah, nevermind I’m wrong. You can edit the formula on the right hand side it seems.

Click the column type in the Hide|Show columns display, then click Add Formula.
