Field visible only if a choice is taken from the list

Hello,

I have an app with sharepoint list.

In one section I have a sharepoint choice list with three choices. I want to be able to make another window appear when one choice is made.

Within Visible section I made this formula:

If(DataCardValue12.selected.value = "Legal Law",true,false), but it does not work.

How can I make this happen?

Where did you put this formula? It should go in the Visible property of the Window you want to appear. Are you getting any error messages?

If(DataCardValue12.Selected.Value = "Legal Law",true,false)

Also, what do you mean by a Window? There is no control called a Window in Power Apps so I'd love to see a screenshot for clarification.

Sorry - I meant another form. Another form appears.

This situation is like that;
I have a list from sharepoint that you can pick one choice out of three.
If you pick Legal Law then another form will appear below that form. If you pick other two nothing will appear.

When I use formula I get an error ParenClose (Formula has an ParenClose in a place wihere it expected Error)?

Also is there any way to make this choice mandatory when it appears?
I do not want to make it mandatory in sharepoint since there might appear some problems (form might be invisible for some requests and it will block the form).

Hi @Elitezone

Can you share more details about the error that you are getting? What is stored in the "Items" property of the dropdown list? Is value a right column to refer? If you can share more details, we might be able to help you better.

There was an extra comma at the end of my code. Also, it appPlease use this code instead.

If(DataCardValue12.Selected.Value= "Legal Law",true,false)

To make the dropdown required we want to disable the Submit button for your form. To do this place the following code in the DisplayMode property of the button.

If(DataCardValue12.Selected.Value=Blank(), DisplayMode.Disabled, DisplayMode.Edit)

I think the error is coming because of small case values passed in the arguments, can you try to update the expression to:

If(DataCardValue12.Selected.Value= "Legal Law",true,false)

Hope this Helps!

Sorry I made a mistake - it should be DataCardValue11 not 12 (11 is a dropdown list). With DataCardValue12 it shows error as above.
When i used it like that:
If(DataCardValue11.Selected.Value= "Zmiana Prawna",true,false)
It showed 3 polish errors (sorry I do not know how to change language):

(ParenClose)
(argument mismatch)

(unexpected sign)

I added it like that. Still Errors.
From now I'll write you details in polish since data in dropdown sharepoint list is also in polish language.
