Setting up a popup warning then clearing once read

Sorry, Newbie here.

I am creating an App using dropdown selection e.g. options A,B,C,D. If a user selects A (and none of the others) I want to have a message popup to tell them they have to complete a specific text box with justification.

I can get the popup to appear by setting the Visible property as:

DataCardValue1.Selected.Value="A"

so the user sees the message.

But I can't see how to add in an action so the user can confirm reading and close the popup, such as by clicking a cancel icon. The selected value A would remain so I guess the popup's Visible property will remain true. Please can someone advise what I'm missing? Thanks in advance.

Option 1:
Powerapps has out of the box functionality for a popup quick notification on top of the page; which disappears automatically. If you are interested, this would be the easiest way to go. Insert the below code on the OnChange property of the DropDown:

//Notification Pop Up on when OPtion "A" is selected from Dropdown //OnChange property: If(Dropdown1.SelectedText.Value = "A", Notify("Please complete a specific text box with justication",NotificationType.Warning))

Dopdown1 - is the name of the control in my app. You will probably need to replace is with DataCardValue1.Selected.Value

Option 2:
If you want to have a physically screen (object) that blurs everything out and forces your users to read your pop up. You can use this method.

In the OnChange Property of your dropdown, set a variable to "true" which will control the visibility of the your popup:

Set(varIsVisiblePopUp, true)

Set the Visible property of your Pop Up to this variable

//Visible property of Pop Up varIsVisiblePopUp

If your popup has a cancel(close) button or icon, use the OnSelect property to toggle the varIsVisiblePopUp variable to false. This will then hide your popup.

//OnSelect property of Cancel/Close button or icon Set(varIsVisiblePopUp, false)

Lastly, you will always want to hide the pop up when the user first visits the screen; so for good measure, I would default the varIsVisiblePopUp to false when the screen becomes visible. To do this, go to the OnVisible property of the screen and set varIsVisiblePopUp to false.

//OnVisible property of Screen Set(varIsVisiblePopUp, false)

Either option should work. Good luck.

You may want to use a variable, and use a container for your popup. You can add multiple components to the container (your warning, an icon, even your text box). Set the visible property to
DataCardValue1.Selected.Value="A" And varA

That way you can hide it by toggling your variable to false. This can be done via your icon in the container.

App OnStart:
Set(varA, true)

"Cancel" icon
Set(varA,false)
