Problem with SET property

[nicolaslegall]

Hello, 

I'm trying to build a powerapps calendar application, but to upgrade my calendar, i'm trying to use the "Set" function like " Set( _dateSelected, Today() );" or  "Set( _firstDayOfMonth, DateAdd( Today(), 1 - Day( Today() ), Days ) );" like in this documentation : https://docs.microsoft.com/fr-fr/powerapps/maker/canvas-apps/screen-templates/calendar-screen-overvi...

But this display a error, is the documentation outdated or am I doing something wrong ?

Thanks for your answers.

You are missing a ";" in the end of Set

Set(_dateSelected, Today() );

If this does not solve your problem, please put the mouse over the error and tell me te error

Hello @Nogueira1306 , thanks for your answer,

Even with "Set( _dateSelected, Today() );", it's not working, and I got 2 errors "number of invalid arguments : 1 were received, 2 were expected", and "unexpected characters, the formula contains "ParentClose" while "error" is expected.".

Moreover, when I overview the Set function, it tells me the syntax "Set(variable; value)", that's why i'm asking about documentation that is outdated.

Documentantion is notoutdated. That has to do with Power apps language and location.

In US tehy use "," over ";". In Portugal we use ";" for example. YOu need to check your region

@nicolaslegall ,

Depending on your region your code will be either

Set(
   _dateSelected,
   Today()
);
Set(
   _firstDayOfMonth, 
   DateAdd(
      Today(),
	  -1,
      Days
   )
);
Set(
   _firstDayInView,
   DateAdd(
      _firstDayOfMonth,
      -(Weekday(_firstDayOfMonth) - 2 + 1),
      Days
   )
)

or

Set(
   _dateSelected;
   Today()
);;
Set(
   _firstDayOfMonth; 
   DateAdd(
      Today();
	  -1;
      Days
   )
);;
Set(
   _firstDayInView;
   DateAdd(
      _firstDayOfMonth;
      -(Weekday(_firstDayOfMonth) - 2 + 1);
      Days
   )
)
