Hi @Anonymous ,
Could you please share a bit more about your scenario and the layouts?
Do you want to limit the users to edit on the Gallery screen and save on the detail form screen?
Or users could turn to detail screen without limitation but only users’ names meet the three field’s content could see or click the Edit Button?
And what are the field TYPE of the three column you mentioned in the post, Person or Text?
I assume they are Person type fields.
First of all, on the Gallery screen, set screen’s OnVisible to
Set(varUser, User().FullName)
Then if the Edit Button is on the Gallery screen, like the right arrow of the Item of below screenshot, set the Edit Button’s Visible to
If(varUser = ThisItem.SME.DisplayName || varUser= ThisItem.Responsible.DisplayName || varUser= ThisItem. ‘Asigned To’.DisplayName)

On the Edit form screen, set Save Button’s DisplayMode to:
If(varUser= DataCardValue1.Selected.DisplayName || varUser= DataCardValue2.Selected. DisplayName || varUser= DataCardValue3.Selected. DisplayName, DisplayMode.Edit, DisplayMode.View)

If you want to limit users editing after they enter the details screen, so the Edit Button is on the Details Screen, then also set Edit Button’s DisplayMode to the above formula.
