How can I display an Icon on another screen when a certain field is empty in a gallery, then when the field gets completed, the icon disappears. Would a global variable be the best option?

Eg. a user creates a record and fills out the Start Odometer but not the End Odometer. On the home screen of the app, the user is reminded they have an incomplete entry as a icon is displayed.

I have managed to get an icon visible by using 'If(IsBlank(Label21_1), true, false)' in the visible properties of the icon and where Label21_1 is the end odo field in my gallery, however the icon does not show straight away, until I hard close and re-open the app, and still then its a bit hit and miss.

Thanks

Yes, Whatever button you have after this screen. You can set the global variable on that button's onclick. It will be more reliable

Thanks @zmansuri

What we be a simple way to achieve this?

Are you talking about the 'OnSelect' property of the submit button on my submission form screen?

Something like-
If(IsBlank(EndOdoLabel.Text), Set(IconVar, true)

You can use it anywhere according to your business logic. The whole point is you can control the flow.

But yes the code will be same.
