Why is my value not being saved?

I am trying to save the result of Text(Now(), "[$-en-US]ddd") as a variable.

If I set the Text of a Label control to Text(Now(), "[$-en-US]ddd"), this works fine. Today it displays 'Thu'

I want to use this value to provide default data.

I have tried UpdateContext({gvDayName:Text(Now(), "[$-en-US]ddd")}); and Set(gvDayName,Text(Now(), "[$-en-US]ddd")); in the OnVisible property of my screen.

When I run it and view the variables, gvDayName has no value.

Why is this not working?

Your code 100% works. However, it only runs when you change screens 🙂

Put this code in the OnVisible property of the screen

Set(gvDayName,Text(Now(), "[$-en-US]ddd"))

Next, put this code in the OnHidden property of the screen.

Set(gvDayName,Blank())

Create a new label and use this code in the Text property.

gvDayName

Now click on a different screen in PowerApps Studio. Then click on the screen you placed the label in. It should work!

Thanks @mdevaney - but that does not make any sense.
I have already put this in my OnVisible property, and it does not work. 100%
Everything else I have put in there does work, and there is a lot of it. Too much for these tiny frames, if you ask me:

Set(LoadingSpinnerVisibility,true);
Coalesce(gvSelectedYear, gvDefaultYear);
Coalesce(gvWeekNo,gvDefaultWeek);
Coalesce(gvStartOfWeek, true);
If(gvStartOfWeek, UpdateContext({toggle2:true, toggle3:false, toggle4:false, toggle5: false, toggle6:false}));
If(gvStartOfWeek, Set(gvStartOfWeek, false));
ClearCollect(outstandingOrders,GoodsInToday.Run(gvWeekNo, gvSelectedYear, gvDaySelected)
);
Set(LoadingSpinnerVisibility,false);

I have chosen a Global Variable so that it will hold it's value when I change screens, so why would I want to do Set(gvDayName,Blank())?

I have also tried putting this in the OnStart property of the App. The line above it works. Why not this?

Set(gvDefaultYear,
Value(Text(Today(),"[$-en-US]yyyy")));
Set(gvDayName,(Text(Today(), "[$-en-US]ddd")));
Set(gvDefaultWeek,
If(RoundDown((Today() - Date(Year(Today()), 1, 1) + (Weekday(Date(Year(Today()), 1, 1) - 1, Monday))) / 7, 0) = 0,
52,
RoundDown((Today() - Date(Year(Today()), 1, 1) + (Weekday(Date(Year(Today()), 1, 1) - 1, Monday))) / 7, 0)+1)
);
Set(gvDefaultDay,2);
Set(gvDaySelected, gvDefaultDay);
Set(gvSelectedYear, gvDefaultYear);
Set(gvWeekNo,gvDefaultWeek);
Set(gvStartOfWeek, true);

OK. This problem has solved itself. I had to close the app in the edit screen & reload it. Then it worked.
